My name is Douglas Stebila. I’m a lecturer at the Queensland University of Technology and recently completed my PhD in mathematics at the University of Waterloo. My interests include cryptography, computer security, mathematics, music, running, photography, and travel.
I maintain a blog that I try to update relatively frequently (though sometimes fail to do so!).
I currently work at the Queensland University of Technology as a Lecturer jointly appointed between the disciplines of Computer Science and Mathematical Sciences; I’m also a member of the Information Security Institute. My research focuses on cryptography, Internet security, and quantum cryptography.
A full list of my research publications is available. My most recent papers are:

I completed my PhD in the Department of Combinatorics and Optimization at the University of Waterloo in 2009. My thesis was entitled Classical Authenticated Key Exchange and Quantum Cryptography.
I completed a MSc in Mathematics and Foundations of Computer Science at Pembroke College, University of Oxford, in 2004, and an Honours BMath (Co-op) in Combinatorics & Optimization and Computer Science at St. Jerome’s University in the University of Waterloo in 2003.

I travel a lot and take lots of pictures on my trips. The best of my photos are posted online. My newest galleres are:
