Research

My research is in probability theory. I focus on random graphs on the one hand, and processes motivated by biological applications on the other. In the first area I have been working on sparse Erdős-Rényi graphs, and am currently also interested in geometric graphs. In the second area my work has been on weakly interacting branching processes. I hope to combine these two research directions in the future.
