Machine Learning for Medicine and Science


Open positions

Artificial intelligence holds tremendous promise in enabling scientific breakthroughs and discoveries in diverse areas. We investigate applied machine learning with a current focus on networked systems that require infusing structure and knowledge.

Our research strategy is to create foundational models, including pre-trained, self-supervised, multi-purpose, and multi-modal models trained on broad data at scale. This strategy identifies ways to infuse knowledge, geometry, and structure into AI models to address uncertainty and enable broad generalization. It creates graph AI machines that produce actionable representations to advance the biological problem past the state of the art and open up new opportunities.

AI for Medicine

The state of a person is described with increasing precision incorporating modalities like genetic code, behaviors, therapeutics, and the environment—the challenge is how to reason over these data to improve decision making. Our research creates new avenues for accelerating the development of therapeutics, fusing biomedical knowledge and patient data, and giving the right patient the right treatment at the right time to have medicinal effects that are consistent from person to person and with results in the laboratory.

AI for Science

For centuries, the method of discovery—the fundamental practice of science that scientists use to explain the natural world systematically and logically—has remained largely the same. We are using artificial intelligence to change that. The natural world is interconnected, from all facets of genome regulation to molecular and organismal levels. These interactions at different levels give rise to a bewildering degree of complexity. Our research disentangles this complexity and develops artificial intelligence tools to guide discovery in biomedical sciences and produce interpretable outputs that lend themselves to actionable hypotheses.
