I am a mathematician working on arithmetic geometry and quantum computing, with interests in post-quantum cryptography and mathematical physics.
I received my PhD in Mathematics from the University of Auckland, where I worked under the supervision of Steven Galbraith.
After my PhD, I held research and teaching roles in the Department of Mathematics at the University of Auckland, before joining the University of Manchester.
The research I have chosen to share publicly includes mathematical foundations for post-quantum cryptography. In this line of work, I introduced the Hecke problems, the noisy subset product problem, and unknown-coefficient multivariate exponential equations.
I have also introduced the nonintrinsic sector of Landau theory, continuum free-energy computing, and unknowable quantum communication.
I am the organiser of the Manchester Interdisciplinary Seminar connecting mathematics, physics, and computer science. I also co-organise UK Crypto Day and UK Isogeny Day.
I am a Co-Investigator (CoI) on the QRL-funded project Post-Quantum Adaptor Signature Schemes for Blockchain Protocols at the University of Manchester, working with Bernardo Magri and Tako Boris Fouotsa.
