A Pathway to Longer-Lasting Lithium Batteries
The energy density of batteries have been a major challenge for consumer electronics, electric vehicles, and renewable energy sources. Professor Julia R. Greer has made a discovery that could lead to lithium-ion batteries that are both safer and more powerful. Findings provide guidance for how lithium-ion batteries, one of the most common kinds of rechargeable batteries, can safely hold up to 50 percent more energy. "Every power-requiring application would benefit from batteries with lithium instead of graphite anodes because they can power so much more," says Greer. "Lithium is lightweight, it doesn't occupy much space, and it's tremendously energy dense." [Caltech story]
Ari Rosner Develops Tool That Configures Socially-Distanced Students In Classrooms
Mechanical engineering student Ari Rosner, has developed an interactive Excel worksheet powered by advanced algorithms to help schools with social distancing in classrooms. Schools can plug a room’s dimensions and social distancing parameters into the worksheet, and the most efficient configuration of students for a designated classroom would automatically be mapped out. Rosner’s model situates students in rows or in a hexagonal pattern, depending on a room’s shape, in order to safely maximize space. "I cried when I saw how this worked," said Rachael Burton, the development director at a small private school in Brooklyn, New York. "I knew Ari’s mathematical chart could save our lives."

Machine Learning Helps Robot Swarms Coordinate
Soon-Jo Chung, Bren Professor of Aerospace, Yisong Yue, Professor of Computing and Mathematical Sciences, postdoctoral scholar Wolfgang Hönig, and graduate students Benjamin Rivière and Guanya Shi, have designed a new data-driven method to control the movement of multiple robots through cluttered, unmapped spaces, so they do not run into one another. "Our work shows some promising results to overcome the safety, robustness, and scalability issues of conventional black-box artificial intelligence (AI) approaches for swarm motion planning with GLAS and close-proximity control for multiple drones using Neural-Swarm," says Chung.

Alexander Popov Receives 2020 Henry Ford II Scholar Award
Computer science student Alexander Popov, advised by Professor Yaser Abu-Mostafa, is a recipient of the 2020 Henry Ford II Scholar Award. Some of the most interesting classes that Alexander has taken at Caltech have been team-based interdisciplinary project classes. These classes have allowed him to gain experience working in teams with varying specialties, while designing and implementing interesting projects (for example, a robot arm designed to recognize users’ hand gestures and assist them in executing complicated drawing-related tasks, such as exactly copying an area of a whiteboard). This summer he will be working as a software engineer at Facebook. After graduation, he aims to work at a company where he is able to further develop his knowledge of machine learning and the application thereof. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

June Kim Receives 2020 Henry Ford II Scholar Award
Computer science mathematics student Joo Eun (June) Kim, advised by Professor Adam Wierman, is a recipient of the 2020 Henry Ford II Scholar Award. June is largely interested in software engineering and game programming. She has previously worked at NASA Jet Propulsion Laboratory as part of the Mars 2020 Lander Vision System team, and at Blizzard Entertainment as a full-stack engineer intern. This summer she will be working at Riot Games as a game engineer intern and is hoping to continue her professional career in the gaming industry. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.
