01 About
I am an Associate Professor at the University of Sydney, a member of the Algebra Group, and Associate Head (Research) in the School of Mathematics and Statistics.
My work brings together representation theory, geometry and combinatorics. I am interested in categorical structures, the geometry of braid groups, and new ways of discovering mathematics with machine learning.
I completed my PhD at UC San Diego in 2009, and held postdoctoral positions at the University of Toronto and Tel Aviv University before moving to Sydney.
