COMMENTARY: Improving access to computer science can help … – EdSource
After several years of school on Zoom, watching YouTube how-to videos about anything and everything, and talking via Snapchat, its tempting to think that students are already equipped for our technological future. But technology innovations like artificial intelligence and ChatGPT are wreaking havoc on our education system.
As education headlines are dominated by calls to catch up from the pandemic and build a more equitable schooling system, its understandable why wed want every dollar of educational investments going into reading, math and other basic skills. But California is facing a more fundamental problem: Because we havent yet reached equitable access to high-quality instruction across the curriculum, we have to invest in our future, without exacerbating existing inequalities.
As educators and policymakers consider ways to increase student achievement, its important that we ensure equity in expanding teaching and learning opportunities. In our increasingly digital world, computer science is a necessary building block that enables students to develop foundational skills that apply across subjects, from computational thinking and interdisciplinary problem-solving, to collaboration and digital citizenship. Importantly, computer science also plays a unique role in supporting learning and student engagement when it is integrated into more traditional subjects like math, science, arts and the humanities in large part because technology is the currency for learning among our youth, and critical to success in college, careers and life.
The pandemic propelled a nearly overnight transformation of our education system and the rapid proliferation of remote learning. Consequently, students are online more than ever before. It is critical to help young people understand and demystify computing technology as well as consider its ethics and impacts like biased algorithms that lead to unfair policies and practices, the entrance of AI into classrooms and workplaces, and the impacts of social media on self-image and mental health. Like math and reading, a computer science education is foundational to developing a well-informed, well-equipped citizenry in todays world.
Moreover, computer science helps prepare students for college and opens the door to some of the highest-paying and fastest-growing careers. The Bureau of Labor Statistics projects that employment in computer and information technology occupations will increase 13% from 2020 to 2030 equivalent to about 667,600 new jobs which is faster than the average growth for all occupations. And, the median annual salary for computer and information technology occupations was $91,250 in May 2020, higher than the median annual wage for all occupations of $41,950. California is a leader in the technological revolution, leading the nation in tech employment (1.88 million tech workers) and the economic impact of the tech sector ($520 billion), and home to fiveof the top 10highest-grossing global tech companies.
Failing to provide our students the opportunity to learn computer science will only increase existing disparities in student success and representation in top-tier industries.
Despite the importance of equitable access to computer science education, only 39% of California high schools offer computer science courses, and only 5% of students are actually enrolled in them. (The most recent publicly available data from the California Department of Education is from 2018-19.)
Offering all California students a computer science education especially girls, low-income students and students of color will open the door to economic opportunities and high-paying jobs from finance to farming, healthcare or entertainment. This will also ensure California has the skilled and diverse technological workforce needed to maintain competitiveness and drive innovation in our state.
The California Legislature is considering two important computer science bills: Assembly Bill 1054 (Berman), a bill that will require all public high schools to provide at least one computer science course; and Assembly Bill 1251 (Rivas) that will expand the pool of teachers to teach it. These policies will be integral in bolstering student achievement with relevant future preparation by equipping our students for their technological future. This means investing in computer science education and ensuring all students including low-income students and students of color have access to this foundational knowledge for their future.
Providing access to computer science in all high schools will help our students catch up while moving ahead. Computer science education can help us do both.

Internet inventors Cerf and Kahn to join President Chiang for … – Purdue University
WEST LAFAYETTE, Ind. Vint Cerf and Robert Kahn, the tandem credited with founding the Internet in the early 1970s, will join Purdue University President Mung Chiang for a Presidential Lecture Series event in September, coinciding with the 60th anniversary celebration of Purdues historic launch of the nations first academic computer science department.
The discussion with Cerf and Kahn, who are commonly called the Fathers of the Internet, is planned for Thursday, Sept. 7. The time and location will be announced later. The Presidential Lecture event, which is free and open to the public, is titled Origins of the Internet and its Subsequent Evolution and comes a half-century since the pivotal period of Cerf and Kahns groundbreaking work.
As Purdue continues the yearlong celebration of thenationsfirst computer science department 60 years ago and launches new investments, such as 50 new faculty in computing departments, to attain the pinnacle of excellence,it is particularly exciting to bring to our campus the two pioneersof the Internetwhopaved the way forone oftheplanet-changing innovationsofourInformation Age,Chiang said.Vint Cerf and Robert Kahnare true American trailblazers, and their Presidential Lecture at Purdue coincides with their inventing the TCP/IP half a century ago.Their creativity and persistence define the very essence of pinnacle of excellence and impact.
Cerf and Kahn led the design and implementation of what formed the basis of the Internet, beginning with their seminal research paper in the early 1970s. Titled A Protocol for Packet Network Intercommunication, the paper was subsequently published in the iEEE Transactions on Communications in May 1974 and outlined the resulting Internet architecture for the technological innovation thats ubiquitous today.
In a mere six months in 1973, Cerf and Kahn crafted the common digital language that provides the pathways for interconnecting vast network devices. They developed the Transmission Control Protocol, which later split off the Internet Protocol, becoming TCP/IP, seen in the network settings of computers to this day. In geek speak, they formulated fundamental protocols for wireless and wired networking, specified TCP/IP to meet these requirements, prototyped TCP/IP and coordinated early TCP/IP implementations.
They first met when Kahn came to UCLA in 1969 to help test the nascent Advanced Research Projects Agency Network, known as ARPANET. Kahn and Cerf formed an effective working relationship to generate test data and predict and diagnose problems in the network. Later they began work on the Internet, completing their design in the fall of 1973. The effort spanned more than 10 years, and the birthday of the operational Internet is Jan. 1, 1983. In the ensuing decades, computer networks across the globe were able to communicate with each other using protocols developed by Kahn and Cerf.
Cerf received a bachelors degree in mathematics from Stanford University in 1965, then spent two years at IBM, where he contributed to QUIKTRAN, a FORTRAN based time-sharing system. Drawn to the field of computer science, he left IBM to study at the University of California, Los Angeles, where he earned his masters degree and PhD in computer science in 1970 and 1972, respectively.
Kahn earned a bachelors degree in electrical engineering at the City College of New York in 1960 before earning his masters degree in 1962 and PhD in 1964 in electrical engineering from Princeton University. His first job was with AT&T Bell Labs before he joined the electrical engineering department at Massachusetts Institute of Technology as an assistant professor in 1964. Kahn took a leave of absence from MIT in 1966 to work at a local research and development firm, Bolt, Beranek and Newman (now known as Raytheon BBN), where he began developing his own ideas for computer networking.
For their global-changing achievements, Cerf and Kahn have collected countless awards, including the Presidential Medal of Freedom, the highest civilian honor in the U.S., as well as the ACM A.M. Turing Award, the highest distinction in computer science; the U.S. National Medal of Technology and Innovation, the highest technology honor; the Japan Prize, that countrys most prestigious honor for science and technology in 2008; and many honorary doctoral degrees.
Purdues advancing computer science legacy
Sixty-years ago, Purdue celebrated the launch of its groundbreaking computer science program when it dedicated its new high-speed IBM 7090 digital computer. Today, Purdues computer science program is the largest and most selective on campus, with 2,405 undergraduate and 538 graduate students enrolled as of Fall 2022.
And just two weeks ago, Purdue unveiled its Purdue Computes initiative, which will provide vital strategic investments for faculty hires, artificial intelligence research and semiconductor facility upgrades, with the goal of becoming one of the top 10 computer science programs in the U.S. by the end of the decade.
About the Presidential Lecture Series
Launched in 2014 by then-Purdue President Mitch Daniels and continued in 2023 by President Mung Chiang, the Presidential Lecture Series exposes Purdue students and the broader community to inspiring ideas, courageous leadership and models of civic engagement and civil discourse.

Osage embraces computer science and technology – Globe Gazette
Education is increasingly becoming technology driven. The Osage Community School District is ahead of the curve in its focus on this other form of literacy.
From left to right, Marley Hannon, Ava Ketelsen and Hayden Huisman use technology at Lincoln Elementary School.
Computer science is one aspect of Osages efforts. Recently, its determination was honored, when Lincoln Elementary School received a CS100 School award for its commitment to providing exceptional computer science education to its students.
Lincoln was one of only two schools in Iowa to receive the national recognition.
To be eligible for the CS100 School award, Lincoln had to meet minimum requirements of teaching 10 hours a year of computer science. According to Osage media specialist and technology instructional coach Kelley Molitor, the school at every grade level spends over two hours a week coding writing computer programs.
We qualified very easily for it, Molitor said, adding she was very confident in Osages application. We do a lot of coding throughout the day. Its not a standalone here. Its infused throughout the grade levels. Coding happens during literacy, math, science and social studies.
People are also reading
As John Pearce, executive director of the awarding body CSisElementary believes, computer science is a literacy.
Molitor is more emphatic, stating that what is taught in Osage affects all of Mitchell County, as students eventually join the workforce and bring their skills to bear. Even agriculture is now driven by computer science. Computer science helps feed the world. The medical field is immersed in it, and what the students learn today could save lives tomorrow.
Anyone who uses a cell phone is part of the movement.
One of the instructors conveying this knowledge and these skills is Lincoln Elementary School teacher Lori Randall. It is no longer science fiction when robots assist the students in their classrooms.
Each grade level has a different device that they master, Randall said. Its sequential from kindergarten through grade four in our building.
By the time these students reach middle school, they are experts. Randall believes Lincolns CS100 School award was well deserved. She sees her students coding and guiding robots through obstacle courses every day.
We were really proud to have won that, because everyone is part of this journey, Randall said. Its not just certain teachers. All of us are working together. We go above and beyond in this area. Youre starting young with the problem solving, the computational thinking, the creativity, the communication and the collaboration. And then we keep building on it every year.
These kids have had computers and technology in their hands since they were born, Molitor said.
STEAM
Another aspect of Osages emphasis on technology was the STEAM Festival held last month. Exhibits filled the gyms and classrooms of the middle school and high school. STEAM is an acronym for science, technology, engineering, arts and mathematics.
Most of the elementary teachers were involved in the event. For an evening, their students became instructors.
Just inside the front door, a state-of-the-art robot dog performed tricks for kids.
Molitor helped organize the event, which was sprawling. People came from other school districts. There were drones, star labs and almost every technology conceivable. Participants could peer into microscopes and hammer nails. It was a combination of technology brought into the school from outside sources, as well as a showcase of the students and the schools own technological efforts.
We have a lot of support in the community as well as around the area, Molitor said, as Iowa State University and the U.S. Army were represented, along with local businesses, the police department and the hospital.
Going low tech at the STEAM festival.
Still, the star of the show might have been the robot dog, which is an over-simplified way to describe the device. It walks on four legs with the sophistication of an animal.
Molitor envisions how that technology could translate to cyber security in a school. The robot animal could not only teach programming, but cameras could be installed and it could patrol the halls as a guard dog. The applications are endless. It is the sort of creature that ends up on Mars.
While a robot as a hall monitor is a few years out, Molitor would like one day for the school to be able to afford this sophisticated device.
The handler of the robot dog visited administration at Osage last summer. The robot uses what is called C++ programing, which is a high-level language.
Our high school graduates who are in college now have told us we need to keep getting other languages in the high school, Molitor said of programming. So our students can learn more before they get to college. The cool thing about this robot dog is that it could be coded in C++.
Realism in movement will soon give way to realism in thought, to what is known as artificial intelligence.
With AI, that stuffs going to start thinking, Molitor said. Even that robot dog would have AI, so it would recognize people. If we took the whole school, and put every photo into the dogs memory, then it would identify someone who was not supposed to be there.
Kelley (Molitor) is great at inspiring and encouraging people, Randall said, as Molitor is a driving force in recommending technology and writing grants to afford it. To her, it is well worth the money, whether it is simple coding or a robot.
We wouldnt be here without her, said Lincoln Elementary School instructional coach Deb Huftalin. She knew what was coming and got us started eight years ago.
The STEAM festival highlighted not only what Osage could do, but how it could expand with more resources.
Job simulator
Another technological advancement is being shared between Osage and the St. Ansgar Community School District. It is a job simulator, which was featured at the STEAM festival. It will be operated out of the industrial technology program.
It was a year in the making with the STEM BEST grant and other monies we could generate, Molitor said, as local businesses helped with the financing.
While some students learn best by the book, there are others who thrive outside the classroom setting, which is not unusual in a farming community, where skills are learned through practice.
Occasionally, it will help students know what they dont want to do.
The Osage and St. Ansgar Community High School job simulator.
We have a lot of kids who are hands-on learners, Molitor said. Many businesses need kids that have the skills to do the jobs they need. The businesses are able to use the job simulator for training. Theyre very hopeful theyll get employees out of it.
One goal is to keep students local after they graduate. Another of Molitors goals is to get more girls interested in hands-on occupations.
And as Molitor notes, it is better to fail on the job simulator than on an expensive piece of equipment.
I think its a unique opportunity, Molitor said. I dont know of any other high school in the state that has this. As our kids learn more, we have to keep pushing them and providing what they need.
And what they need is different among different students.
Our students are very excited about learning and infusing it into their reading, Randall said of the crossover between technology and all subjects. Its another opportunity for them to learn in a different way, because all of them are different kinds of learners.
Big schools
While some students are more talented than others, Randall sees technology as leveling the playing field. Because they all have to adapt to what we call being a risk taker it may be wrong, but you can go back and debug and work on it to get it right. Theyre not afraid of failure. They learn from it.
Sometimes its the kids you dont expect, Huftalin said. Theyre not always your high flyers.
Sometimes its the kids who are more quiet and reserved, Randall said.
Molitor also speaks of digital citizenship and online safety.
Its one of the more dangerous times in the world because of online issues, Molitor said. How do you keep yourself safe?
Other much larger schools have praised Osages program. At a conference the previous week, the superintendent of the school system in Bettendorf approached Huftalin with a heap of praise.
She said, We dont do any this this is amazing, Huftalin explained. We take it for granted that weve been incorporating it for almost eight years.
We get calls all the time, Molitor said. It reinforces that were doing the right things.
School systems from across Iowa come to Osage to study its commitment to technology, to learn and then implement Osages system into their own schools. It is a testament to the vision of Osages teachers.
They come to see what were doing at each grade level, said Randall. They see the progression, how were incorporating computer science into our curriculum.
According to Huftalin, between 80-90% of schools have a standalone teacher where students go to learn about computer science. In Osage, they incorporate those lessons into the daily curriculum, which requires a commitment from teachers at all grade levels.
To infuse it is so much more successful, Molitor said, noting that Osage moved from the standalone model early on. It engages kids more.
Kids are growing up in a technology immersive world. If we dont teach them how to use it responsibly, to become creators instead of just consumers, then were not giving them the tools they need to be successful after high school.

Ethan Hodge named Arkansas Computer Science Educator of the … – Russellville Courier
Russellville High School Computer Science Teacher Ethan Hodge was named the 2023 Arkansas Computer Science Educator of the Year on Saturday, April 29 at the Arkansas State Coding Competition.
Hodge will be receiving $15,000 from the Arkansas Department of Education in recognition of this award. Hodge is one of five finalists in the state.
The selection process is through the Arkansas Department of Education in which applicants must demonstrate a strong commitment to Computer Science education in their school and community. Applicants submit information on their career history, letters of recommendation, a series of reflection questions, and a video lesson demonstrating their strengths in the classroom.
I believe my students should be able to break down complex problems, develop solutions, and be collaborative participants in a technology rich society, Hodge said. These skills are the primary focus of Computer Science Education and can serve students in all aspects of life, regardless of the direction they choose. This is why I believe in Computer Science education.
Hodge has served in RSD for nine years. Currently, Hodge teaches computer science at the Russellville High School and serves as a Robotics coach where he has led the students to five State Champion titles. In 2022, Hodge was named the Russellville High School Teacher of the year.
There are many great Computer Science educators in Arkansas. Earning this title is a tremendous honor and it feels good to know that the work Ive done matters. I am grateful to be part of such a wonderful community that supports its school, an excellent group of educators at RHS, and to have such awesome students, Hodge said.

When Art and Science Meet as Equals – Research Blog – Duke University
Artists and scientists in todays world often exist in their own disciplinary silos. But the Laboratory Art in Practice Bass Connections team hopes to rewrite this narrative, by engaging Duke students from a range of disciplines in a 2-semester series of courses designed to join the artist studio, the humanities seminar room, and the science lab bench. Their work culminated in re:process an exhibition of student artwork on Friday, April 28, in the lobby of the French Family Science Center. Rather than science simply engaging artistic practice for the sake of science, or vice versa, the purpose of these projects was to offer an alternate reality where art and science meet as equals.
Liuren Yin, a junior double-majoring in Computer Science and Visual and Media Studies, developed an art project to focus on the experience of prosopagnosia, or face blindness. Individuals with this condition are unable to tell two distinct faces apart, including their own, often relying on body language, clothing, and the sound of a persons voice to determine the identity of a person. Using her experience in computer science, she developed an algorithm that inputs distinct faces and outputs the way that these faces are perceived by someone who has prosopagnosia.
Next to the computer and screen flashing between indistinguishable faces, shes propped up a mirror for passers-by to look at themselves and contemplate the questions that inspired her to create this piece. Yin says that as she learned about prosopagnosia, where every face looks the same, she found herself wondering, how am I different from a person that looks like me? Interrogating the link between our physical appearance and our identity is at the root of Yins piece. Especially in an era where much of our identity exists online and appearance can be curated any way one wants, Yin considers this artistic piece especially timely. She writes in her program note that my exposure to technologies such as artificial intelligence, generative algorithms, and augmented reality makes me think about the combination and conflict between human identity and these futuristic concepts.
Eliza Henne, a junior majoring in Art History with a concentration in Museum Theory and Practice, focused more on the biological world in her project, which used a lavender plant in different forms to ask questions like what is truthful, and what do we consider real? By displaying a live plant, an illustration of a plant, and pressings from a plant, she invites viewers to consider how every rendition of a commonly used model organism in scientific experiments omits some information about the reality of the organism.
For example, lavender pressings have materiality, but theres no scent or dimension to the plant. A detailed illustration is able to capture even the way light illuminates the thin veins of the leaf, but is merely an illustration of a live being. The plant itself, which is conventionally real, can only further be seen in this sort of illustrative detail under a microscope or in a diagram.
In walking through the lobby of FFSC, where these projects and more are displayed, youre surrounded by conventionally scientific materials, like circuit boards, wires, and petri dishes, which, in an unusual turn of events are being used for seemingly unscientific endeavors. These endeavors illustrating the range of human emotion, showcasing behavioral patterns like overconsumption, or demonstrating the imperfection inherent to life might at first glance feel more appropriate in an art museum or a performing arts stage.
But the students and faculty involved in this exhibition see that as the point. Maybe it isnt so unnatural to build a bridge between the arts and the sciences maybe, they are simply two sides of the same coin.

Reality and Robotics Lab Looks to the Sea – Dartmouth News
Thousands of construction projects around the world involve building infrastructure in shallow coastal areas. Some support aquaculture and offshore wind energy projects, while others erect seawalls to prevent coastal erosion.
They are expensive endeavors in a harsh environment constantly rocked by waves and swells. With that in mind, Dartmouth researchers are taking the first steps towards creating robots that can dive in and do the heavy lifting.
Underwater construction adds constraints that robots and drones operating on land dont deal with, says Samuel Lensgraf, a computer science PhD student at the Guarini School of Graduate and Advanced Studies. Waves and silt make it impossible to have precise control or a clear view of the operating area.
Lensgraf, working with computer science professors Alberto Quattrini Li and Devin Balkcom, set out to design a construction process that can absorb some of the errors caused by the difficult environment.
One method is to insert custom-made cones through holes in store-bought concrete building blocks. The next layer of blocks slide into place over these cones. This interlocking system ensures that the blocks can be stacked precisely even if they are buffeted by waves as they are set down.

The aquatic robot to work with such a system was designed from scratch. Lensgraf, who was a web developer before joining the Reality and Robotics Lab, was interested in construction and fabrication but had no experience building mobile robots. I did most of the fabrication and engineering; it was really a lot of fun to learn how to do, he says.
Their prototype, which they have tested in a 13-foot-deep swimming pool, can build structures using 12 components and weighing more than 200 pounds.

At the robots core is a claw-like manipulator which draws design inspiration from stone grabbers of yore and exploit the weight of objects they latch onto to tighten their grasp. But if the robot relied solely on battery power to lift and transport the blocks, which weigh up to 20 pounds apiece, it would run out of juice after laying just a few.
Our robot uses two sources of powera battery as well as a buoyancy boost from compressed air, says Quattrini Li, an assistant professor of computer science. A scuba tank releases pressurized air into four cylindrical chambers that encircle the robot. As the chambers fill with air, they lift the robot, and its load, up.
This is similar to how scuba diving works, Quattrini Li says. By using buoyancy, you can make the robot lighter while its carrying heavy things in the water.
Lensgraf also devised an algorithm that determines how much air is used for each tasklifting, moving, and releasingin order to achieve the most effective use of both energy sources and maximize the number of blocks that can be picked up and placed.
This is the first construction robot thats using buoyancy to help it move things, says Lensgraf, who will present his work at the 2023 IEEE International Conference on Robotics and Automation in May.
While this is an important first step, work remains to be done before the robots will be ready to take the plunge into the ocean for field tests, says Lensgraf, who is already working on upgrades.

High schooler who won record $10m in scholarship offers heads to Ivy League – The Guardian US
US universities
Dennis Maliq Barnes of New Orleans announces he will attend Cornell University this fall to study computer science
The 16-year-old American high schooler who set what is believed to be a US record after collecting more than $10m in college scholarship offers is bound for the Ivy League.
Dennis Maliq Barnes announced on Friday that he plans to enroll at Cornell University for the fall semester to study computer science after his 24 May graduation from New Orleanss International high school. The Ithaca, New York, university only accepts 9% of applicants, and just 7% of its 15,000 or so students are Black like Barnes, according to the US News & World Report.
Today is an exciting day for me and my family, read a statement from Barnes that also thanked his family, his high school community and a local university where he has already accumulated 27 college credits. I look forward to working with Cornell over the course of my undergraduate education.
Barnes gained admission into nearly 190 universities and colleges across the US, with about 150 of them offering him a total of more than $10m in scholarship offers.
Officials at International high maintain that Barnes has attracted more offered scholarship money than any incoming college freshman ever in US history.
In 2019, when she graduated from Early College academy in Lafayette, Louisiana, Normandie Cormier received just under $9.5m in scholarship offers from about 140 schools and sought recognition from Guinness World Records.
Guinness has said it doesnt keep track of such a record. Cormier has said Guinness ultimately told her that it did not find anyone else in the US with more offered college scholarship money than her, but the organization couldnt grant record-holder status to her because of differences with higher education systems elsewhere in the world.
Coincidentally, Cormier chose to attend Xavier University in New Orleans which is about three miles (4.8km) from Barness school and still lives in the city.
Known best to his friends by his middle name Maliq, Barnes is a National Honor Society member whose fluency in Spanish has earned him both a diploma from Spains educational, cultural and sports ministry as well as an award from the countrys honorary consul in New Orleans.
He competed on the basketball and track-and-field teams at his school, which promoted him out of his sophomore and junior years as he maintained an unusually high cumulative grade point average of about 4.98.
Though he is younger than the typical US high school senior, Barnes has already started accumulating college credits through a dual enrollment program offered by Southern University at New Orleans.
Barnes has said he hopes the national headlines his record has drawn will inspire his peers to surpass academic expectations that others set upon them. He has also said he wants prospective college scholars to realize how much academic aid is out there, especially as the US student debt crisis has left more than 45 million Americans owing a collective $1.7tn.
Adierah Berger, the head of International high, said in a statement: Dennis is already a bright star and I know his star will shine even brighter when he sets foot on Cornells campus.
A statement from Cornell congratulated Barnes on his acceptance to the university, saying he, his fellow incoming students and their families had already accomplished much to reach this exciting moment in their educational journeys.
We are excited to welcome this incredible group of future leaders to our campus community in just a few months, Cornells statement said.

Later, the COVID-19 pandemic solidified her ambitions. Feeling helpless amid a pandemic is hard; she wanted to become one of the people working on solutions to treat pervasive diseases. As a high school student, Armstrong believed that her only option for doing this work was to go to medical school to become a doctor. Being a student at Davidson, howeverwhere shes been able to work alongside professors in labstaught her about another option that she loved even more: research.
Ive been able to seek out professors who do the kind of research that Im interested in, she said, and put the techniques I learn in class into practice.
That research has created a path for Armstrong that began in Davidson but extends far beyond it.
As part of our work together, [Susannah and I] spent time in my colleague Laura Hartmann's lab in Duesseldorf, Germany, said Nicole L. Snyder, professor of chemistry. Within the first week, I knew I was working with a highly talented scholar. Her unquenchable thirst for exploring new knowledge landscapes, combined with her impeccable work ethic, led her to solve a research problem we grappled with for years.
Scientists also need a healthy dose of persistence to make strides in research.
What impressed me the most about Susannah was her independence and her ability to persevere despite multiple challenges and setbacks, Snyder said. Every time she hit a roadblock, she found a new road to travel, and when she ran out of roads to travel, she built her own.
Armstrong will continue to pursue research this summer at the National Cancer Institute. After earning her doctorate in synthetic organic chemistry, she intends to conduct translational research to develop treatments for globally pervasive disease.

Bastian, Elisseeff, and Szalay are among 120 members and 23 international members elected this year, the academy announced Tuesday. With the new elections, the total number of active academy members grows to 2,565 and the total number of international membersnonvoting members with citizenship outside the U.S.grows to 526. A full list of new members elected in 2023 can be found on the National Academy of Sciences website.
Bastian combines her expertise in neuroscience and physical therapy to study human movement. Specifically, she has a focus on the effects of disease and damage to the central nervous system on movement in adults and children, as well as how people learn new patterns of movement. Bastian is the chief scientific officer and director of the Center for Movement Studies at the Kennedy Krieger Institute; she is also professor of neuroscience, neurology, and physical medicine and rehabilitation at the Johns Hopkins University School of Medicine. She joined Johns Hopkins and Kennedy Krieger in 2001 from the Washington University School of Medicine in St. Louis.
Elisseef specializes in regenerative medicine, especially using the body's own immune system as an avenue for tissue repair and regeneration. She directs the Translational Tissue Engineering Center, a joint venture between the Wilmer Eye Institute and the university's Department of Biomedical Engineering, and is a professor of biomedical engineering, ophthalmology, materials science and engineering, and chemical and biomolecular engineering. Elisseeff joined Hopkins in 2001 after completing a fellowship at the National Institute of General Medical Sciences. She was previously elected to the National Academy of Engineering and the American Academy of Arts and Sciences, and she received the prestigious NIH Director's Pioneer Award in 2019.
Szalay is an international leader in astronomy, cosmology, the science of big data, and dataintensive computing who has significantly expanded our understanding of the structure formation and nature of dark matter in the universe. He has also led the development of computer architectures that are creating a new paradigm of data-intensive science across multiple fields, including astronomy, radiation oncology, and genomics. Szalay is a Bloomberg Distinguished Professor with appointments in JHU's Krieger School of Arts and Sciences and Whiting School of Engineering, and he directs the Institute for Data Intensive Engineering and Science. He joined Johns Hopkins in 1989 from Etvs University in Hungary and is a fellow of the American Academy of Arts and Sciences.
The National Academy of Sciences is a private, nonprofit institution that was established under a congressional charter signed by President Abraham Lincoln in 1863. It recognizes achievement in science by election to membership, andwith the National Academy of Engineering and the National Academy of Medicineprovides science, engineering, and health policy advice to the federal government and other organizations.
