“Amazon’s gift will have a real impact on our program,” said Yisong Yue, professor of Computing and Mathematical Sciences and co-founder of the AI4Science initiative. “There’s a huge level of demand among graduate students and post-doctoral scholars across campus to leverage the techniques and advantages afforded by using AI and machine learning in their own research.”

“Caltech is uniquely placed to be a leader in AI4science given its interdisciplinary collaborations and small size,” added Anima Anandkumar, Bren Professor of Computing and Mathematical Sciences and co-founder of the AI4Science initiative. “We thank Amazon for supporting this groundbreaking initiative.”

For those students specializing in data sciences, Yue said, “it allows them to be exposed to the datasets and research questions faced by scientists in other fields, as well as in companies such as Amazon, and to push the boundaries of existing AI and machine-learning algorithms to effectively address these questions.”

“At Amazon, we strongly believe that AI should be an integral part of all science, not just computer science,” said Marzia Polito, AWS senior manager of applied science. “We are building products supporting the use of AI in many fields of science and many science-based business applications. We are thrilled to collaborate with Caltech, a world-class institution doing ground-breaking science work, and we are honored to have a chance to contribute to their amazing results. There could be no better evidence toward a future where AI and science thrive together.”

This year’s cohort of Fellows comes from the Division of Biology and Biological Engineering, the Division of Chemistry and Chemical Engineering, and the Division of Engineering and Applied Science, reflecting the broad range of research being explored. The Fellows will apply cutting-edge ML and AI techniques to research areas ranging from neural prosthetics and theoretical chemistry, to the human microbiome.

The diverse interests of the Fellows reflect a trend in AI and machine learning that emphasizes cross-disciplinary research and is in line with the AI4Science focus.

“Today we need students who are experts in their own fields, but who also can communicate across different fields,” Yue said. “Effective communication requires a mix of fundamentally sound rigorous thinking coupled with a broad perspective on how to apply that approach to wide range of domains, in order to reveal and distill the core technical challenges that underlie the pressing problems facing science and engineering research today.”

The AI4Science Fellows program is one component within a larger collaboration between Amazon and Caltech. In the area of AI4Science, Amazon is also providing funds for Caltech’s Carver Mead New Adventures Fund, AWS credits for research projects across campus, and support for AI4Science events to build community and share research results.

Beyond the AI4Science initiative, Caltech and Amazon are collaborating in a number of other areas. A group of scientists within AWS’s Amazon Rekognition team is a part of Caltech’s Innovation Center, a building near campus that houses Caltech corporate collaborators and startups. In 2019, AWS and Caltech also announced a collaboration around quantum computing, which will include the AWS Center for Quantum Computing, set to open later this year.

“Caltech prides itself as being an incubator for concepts like AI4Science and next-generation technologies like quantum computing,” said Caltech’s Kaushik Bhattacharya, vice provost for Research and Howell N. Tyson, Sr., Professor of Mechanics and Materials Science. “Our small size, our relentless focus on the most challenging scientific questions — along with our close-knit community that is interdisciplinary by design — encourage and enable us to always be pioneering in the application of tools and techniques from other fields to all areas of science and engineering. To help make sure our findings have impacts beyond academia, we greatly value our collaborations with partners like Amazon.”
