What I Do
My research focuses on predictive modeling of collective behavior in biological systems using real-world data. How do functional biological aggregates emerge from the behavior of networks of heterogeneous individuals?
I am part of the ASU-SFI Center for Biosocial Complex Systems, a joint venture between Arizona State University and the Santa Fe Institute. Here you can find my CV.
I am especially interested in methods of model selection, inferring simplified models that are necessary for making good predictions when one has limited data and limited computational power.
Specifically, I have worked on conflict in macaques, dynamics and statistics of cellular biochemical networks, and DNA conformational dynamics. I work mainly with computational and statistical methods (often with a physics flavor), which have included sparse coding, statistical model selection, maximum entropy models, continuous time sigmoidal networks, and "sloppy" models.
