Summary of Research

Using tools from statistical physics, stochastic processes and computer science, I currently study evolutionary dynamics in structured populations. In particular, we are working on characterizing the behavior of cooperative strategies on networks similar to those found in real biological, spatial or social settings. This involves studying the dynamics of a mutant or generic "infection" (biological, social, economical or other) spreading throughout a population, whose fitness can depend nonlinearly on its own frequency within the population. We are also investigating the success of such cooperative strategies under the influence of more complex network effects such as indirect reciprocity, where reputation mechanisms can further influence the evolutionary stability of cooperation.
