Omidyar Postdoctoral Fellow

Yoav Kallus is interested in optimization and constraint-satisfaction problems. From a computational perspective, he is interested in developing and describing efficient computational methods to solve such problems. From a mathematical perspective, he is interested in analytical methods to give meaningful bounds on the range of solutions that might exist. And from a physical perspective, he is interested in statistically characterizing the space of possible solutions and the behavior of a system navigating such a space. Packing problems give an attractive illustration of many of the interesting phenomena in this area of research and they are a special focus of Yoav's research. Yoav is interested both in ordered optimal structures, and in disordered suboptimal ones in which systems get stuck.

Trained in physics, Yoav is nevertheless inclined to chasing abstract mathematical questions that may not interest many physicists. Abstract questions afford a neatness that real-world problems lack. They have precise formulations and precise answers, and when we hold in our hand such an answer, it feels concrete, not abstract. Even when the answer is elusive, its existence can be a source of comfort.

Yoav holds a PhD in physics from Cornell University and a BS in physics from Rice University. From 2011 to 2014, he was a postdoctoral fellow in the Princeton Center for Theoretical Science at Princeton University.
