I'm a fifth year graduate student in mathematics at the University of Texas at Austin. My advisor is Cameron Gordon. I'm interested in 3 and 4-dimensional topology, especially the interaction between smooth 4-manifold theory, Heegaard Floer homology and 3-manifolds. I am also interested in triangulations of 3 and 4-manifolds.

Before coming to Austin, I studied at the University of Melbourne in Australia where I completed a Master of Science under the supervision of Craig Hodgson.

Computer programs

Veering is a computer program which can be used to construct veering triangulations of mapping tori as introduced by Ian Agol.
