I am an assistant professor in the Department of Combinatorics and Optimization at the University of Waterloo (since 2023). My interests are cryptography (especially privacy and anonymity) and quantum computing.

Most of my existing research is on estimating quantum attack costs, often with a skepticism of the powers of quantum computers, such as:

• a critique of quantum random-access memory
• CSIDH's quantum security
• the cost to break elliptic curve cryptography with Shor's algorithm

with some recent work on "accumulators", with intended applications for digital credentials.

I completed a PhD at the University of Oxford, supervised by Simon C. Benjamin and Christophe Petit. I have an MMath from the University of Waterloo, which Alfred Menezes and Michele Mosca co-supervised. I have a B.Sc. in math from the University of Regina.
