Research Experience
I am currently a Lecturer at the Queensland University of Technology in the Science and Engineering Faculty, jointly appointed between the School of Electrical Engineering and Computer Science and the School of Mathematical Sciences; I am also a member of the Information Security Institute.
From 2009-2010, I was a postdoctoral researcher at the Information Security Institute at the Queensland University of Technology, addressing cryptographic aspects of denial of service resistance.
From 2004-2009, I was a PhD student affiliated with the Institute for Quantum Computing at the University of Waterloo. I worked with Prof. Michele Mosca on a variety of problems related to quantum cryptography, including an analysis of the cryptographic case for quantum key distribution and the development of quantum coins, a new form of digital cash that makes use of the no-cloning properties of quantum money.
As a PhD student, I was also affiliated with the Centre for Applied Cryptographic Research at the University of Waterloo. My research included analyzing side-channel attacks on elliptic curve cryptography, password authenticated key exchange protocols, and denial of service resistance of key exchange protocols.
In Fall 2001, Spring 2002, and Spring 2003, I was an intern at Sun Microsystems Laboratories in the Next Generation Cryptography project, working with Sheueling Chang Shantz, Vipul Gupta, Hans Eberle, and Nils Gura. Our research focused on next generation cryptographic technologies. I worked on software implementations of elliptic curve cryptography and the ECDH and ECDSA algorithms, and integrated them into the widely used OpenSSL and NSS toolkits. We have had several publications (1, 2, 3, 4, 5) and a technical standard result from our work. I was a visiting researcher again at Sun Labs in Fall 2005.
In 2001, I was an undergraduate research assistant in the Centre for Applied Cryptographic Research at the University of Waterloo. I worked with Prof. Stefan Wolf on problems in information theory.
