I am a senior lecturer in the School of Mathematics and Physics at The University of Queensland, Brisbane, Australia.

I received my PhD in mathematics from The University of Queensland in 2001. My PhD thesis was titled "Quasi Hopf superalgebras and their dual structures". My PhD supervisor was Prof. M.D. Gould. I am also proud to have a Bachelor of Science from UQ.

For most of 2001 I worked at the Distributed Systems Technology Centre (DSTC) as a JAVA programmer/mathematician developing elliptic curve cryptographic software in the framework of the JAVA Security Architecture.

I lived in Tokyo for two years from late 2001 until 2003 while I did a postdoc at the Graduate School of Mathematical Sciences, The University of Tokyo.

Since 2004 I have been a lecturer in mathematics at UQ on various casual and fixed term positions. In September 2009 my position was made continuing.

In 2011 I received an Award for Teaching Excellence from the University of Queensland. This was one of five awarded across the university.

Mathematical Physics

I am a member of the mathematical physics group at UQ. My research interests relate to the structure and representation theory of Lie algebras and superalgebras, related symmetry methods and applications to integrable quantum systems.
