Q: Why are you excited to receive the award?

A: It is an enormous honor to be recognized by the SIAM Activity Group on Data Science. Data science is a rapidly evolving field, and one in which many fundamental questions still remain open. It has been a privilege to contribute to the growth of knowledge in this area and to learn from so many wonderful colleagues and mentors as we all work together to understand the exciting possibilities of this new area of mathematics.

Q: Could you tell us about the research that won you the award?

A: I study optimal transport, a set of tools original proposed in the 18th century and refined in the early 20th century for analyzing the structure of probability distributions. These tools have proven extremely useful in data science, where they have been used to study everything from the genetic development of mouse embryos to the performance of deep generative models. I develop statistical and computational theory to put these applications on a rigorous footing.

Q: What does your work mean to the public?

A: Data science, machine learning, and artificial intelligence are changing our world. But, in contrast to prior scientific revolutions, the theoretical foundations of these advances are still not well understood. My colleagues and I develop mathematical theory that helps us interpret and explain the success of data science methods, with the goal of making them more reliable, robust, and efficient.

Q: What does being a member of SIAM mean to you?

A: As an applied mathematician, SIAM is my mathematical home. Its journals and conferences are the premier venues for disseminating new research and for learning about the most important new developments in my field.
