Mathematics etc.

I am an Acting Assistant Professor at the University of Washington. I was a Postdoctoral Fellow at MSRI for the program in Noncommutative Algebraic Geometry and Representation Theory. Previously, I was at the University of New South Wales where I completed my Ph. D. with Daniel Chan. I am a webmaster for the Australian Mathematical Society Careers webpage. I am a lurker on Mathoverflow.

I work on problems in algebra with geometric flavour. Some keywords relevant to my research: maximal orders, Azumaya algebras, minimal model program, Brauer group/Brauer pair, Hopf algebras, Artin-Schelter regular algebra, McKay correspondence.
