I’m a mathematician and data scientist. I’m interested in the relationship between the behavior of individuals the collectives they comprise. Basic scientific questions concern the forward direction, such as “How do the properties of tissues emerge from those of cells?” Grand challenges of engineering concern the reverse, like “How should I design an individual robot so that the swarm has desirable collective behavior?” These questions lead to a rich interplay of statistical, computational, and physical elements, which makes them difficult and rewarding.
