About Me

• I am an Associate Professor at the Australian National University.
• Member of the Secure Software Systems research group.
• I am also an Adjunct Professor at the Carnegie Mellon University, USA.
• I am also an Adjunct Professor at the Victoria University of Wellington, New Zealand.
• My main interest is cyber security-oriented programming languages but also type systems, software verification, etc.
• Check out our capability enabled secure web language called Wyvern developed in collaboration with Carnegie Mellon University.
• I am interested in anything fun to do with programming languages might work.
• I am always looking for any graduate students, while I may have funding, there may also be funding available via the ANU PhD scholarships scheme.
• Feel free to email me or drop by my office to discuss your options.
