Updated December 2023



Mathematical physicist and quantum information theorist (big pile of qubits thinking about other qubits).

I am currently a postdoc in ETH Zurich, was previously a postdoc at Université de Sherbrooke, and did my PhD and BSc at University of Sydney. My research broadly sits in four buckets: While many of my papers span several categories, I have colour-coded and labelled the papers below by their primary category. Also my files (papers, talks, and posters) are available here, and my full CV is available here.
