- Research interests
- My research interests lie in probability and combinatorics. I
wrote my Ph.D. thesis on various aspects of the structure of random
hypergraphs, with particular emphasis on the use of stochastic process
methods. More recently, I have been working on scaling limits for
various random graphs. I have also worked extensively on processes of
coagulation (or coalescence) and fragmentation. Random trees and
branching processes have played a large part in this research. I am also interested in applications of
coalescence theory to mathematical population genetics. In a rather
different direction, I am interested in random satisfiability problems,
such as random K-SAT.
