Biography

I obtained a B.Sc. (Hons.) degree in Mathematics from the University of Adelaide in 1995, and a Ph.D. in Mathematics from Royal Holloway, University of London in 1998.

My PhD thesis is entitled ``On covers of point sets in finite geometries'' (postscript version or pdf version). The work includes constructions of minimal sets of points covering a line in finite projective planes, as well as a study on a family of extended generalised quadrangles and a construction of a new example. The abstract is available in postscript and pdf formats.

I was a post-doctoral research assistant at Royal Holloway from 1998 to 2001 (EPSRC Grant GL/L78505 - Authentication protocols with asymmetric computing requirements).

I was appointed a lecturer in 2001. My current research interests include combinatorics and finite geometry and their applications in information security. I have been working part-time since 2004.

Academic activities

Teaching

2001-2004: Module leader for two MSc in Information Security courses: Business and Security Issues Raised by Electronic Commerce and Secure Electronic Commerce and Other Applications. I was also part of the team involved in providing consultancy through Royal Holloway Enterprise.
2004-present: Module leader and lecturer for a third year Mathematics undergraduate course ( MT3620 Cipher Systems) and co-lecturer with Dr Carlos Cidfor the postgraduate course ( MT4620 Advanced Cipher Systems).
