I am a posdoctoral research mathematician in the Program for Evolutionary Dynamics at Harvard University. I hold a Ph.D. in mathematics from Boston University. Before graduate school, I taught high school mathematics in Chicago and Boston.
The main goal of
my research is to deepen the mathematical foundations of
evolutionary theory. I develop and investigate
axiomatically-defined classes of stochastic evolutionary
models. The aim of this approach is to formalize
general principles of evolution and prove them as
I am particularly interested in the interplay of spatial or social structure and the evolution of social behavior. While particular models have shown many interesting effects--notably, that spatial dispersal can promote cooperation--they have also revealed som puzzling discrepancies. My research aims to resolve these discrepancies through a mathamtically general, axiomatically grounded approach.
My other interests in evolutionary dynamics include the evolution of mutation rates--both in toy models and in E. coli--and the somatic evolution of cancer.
evolutionary dynamics, I am interested in the power of
information theory to quantify structure, coherence, and
diversity in physical, biological, and social systems.
This thread of my research ranges from the concrete
