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.

  • 2004-2013: Module leader and lecturer for a third year Mathematics undergraduate course ( MT3620 Cipher Systems) and co-lecturer with Dr Carlos Cid for the postgraduate course ( MT4620 Advanced Cipher Systems).
  • 2014 Autumn term: Sabbatical.
  • 2015 Module leader and lecturer for a third year Mathematics undergraduate course ( MT3620 Cipher Systems) and the postgraduate course ( MT5462 Advanced Cipher Systems).
  • 2018 Module leader and lecturur for the third year/MSc course Error-correcting codes (MT3610/5461).
MSc students
I am happy to supervise MSc projects in the areas of
  • Applications of discrete maths in information security / cryptography. In particular the application of difference families in areas of communications and information security.
  • Security and privacy in distributed data storage systems.
  • Anti-jamming techniques.
  • Security in swarm robotics.
  • Any other areas of information security as long as they are interesting!
PhD students
  • Amizah Malip (Secure and private annoucement schemes for VANET). Amizah was awarded her PhD in January 2015.
  • Mwawi Nyirenda Kayuni (Combinatorial properties of frequency hopping sequences).
  • Chatdanai Dorkson.
