Research areas
My research is focused on developing mathematical and computational models to study the dynamics of social learning in online information ecosystems. I study a wide range of problems from simple replicator dynamics to complex collective decisions, with projects spanning Mathematical Biology and Computational Social Science. Much of my recent work has focused on how the cultural evolution of human behaviour interacts with algorithms to produce problems such as misinformation, polarization and echochambers. I am also interested in the cultural evolution of cooperation and social behaviour more broadly, in particular the role of cognitive capacity in shaping the evolution of social interactions. The tools I use are mostly drawn from game theory and mathematical models of population dynamics. My personal website can be found here: . My Google Scholar page is here:
