Research Interest: 

I am interested in biophysical systems where collective responses emerge from a large and structured collection of interacting components. Two systems of main focus are the adaptive immune system (diverse populations of immune cells undergoing real-time evolution to fend off invaders and form memories) and active matter (a condensed matter system comprised of numerous self-driven subunits).   

Internally propelled or externally driven, these systems fall out of equilibrium, while being strongly nonlinear and heterogeneous in space and time. In addition, function and survival pose interesting constraints on their dynamics and organization. As a result, surprisingly complex (e.g. for adaptability) or simple (e.g. for robustness) behaviors arise that often defy intuition.

To decipher the surprise, we develop theoretical and computational models, and make concrete predictions to be tested by our experimental collaborators. We draw on and enliven tools/frameworks in statistical mechanics and concepts in condensed matter physics (e.g. frustration due to conflicting requirements, first observed in ferromagnets, might also underlie the rare and tardy development of cross-reactive antibodies, which are craved for protection against highly mutable pathogens).

We aim to understand how biological success selects physical organizations, as well as how the physical structure feeds back on adaptation to environmental uncertainty. This understanding would guide novel design of vaccine strategies and adaptive materials.
