- 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.
