About Me

I am a PhD student at the University of Melbourne studying with Dr Lawrence Reeves.

My research is in geometric group theory. In particular, I am interest in group splitting. The main question is when does a group splits as a free amalgamation over some subgroups or HNN extension. This question is mostly answered by Dunwoody, Scott, and the other. However, one can also ask: under what condition does a free amalgamation over some subgroups retains an interested group property? For example, Bestvina-Feighn concluded that the free amalgamation over subgroup of two hyperbolic groups is hyperbolic if it has "no long annuli". At the moment, I am looking at applying these ideas to Haken n-manifold as defined by Foozwell.

When I am not thinking about maths, you might find me reading, climbing, caving (rarely now) and running.
