People

I work with a small number of PhD students and collaborators at any one time, typically supervising only one or two new PhD students per year. This lets me spend time with each person and support them in developing as independent researchers.

My group operates as a small research community: people come together around questions of computation, arithmetic, hardware, and machine learning, with an emphasis on mathematical and structural understanding. Former students have gone on to research, engineering, academic, founder, and leadership roles across semiconductors, major technology labs, startups, finance, and universities.

Current students

Direct supervisees

  • Ebby Samson – Quantisation, arithmetic optimisation, hardware-aware ML
  • Bardia Zadeh – Novel computer arithmetic for machine learning
  • Ben Zhang – Compiler flows in the age of AI

Students I co-supervise or support

  • Chengyang Ai – e-graph semantics, abstract interpretation (primary supervisor: Jianyi Cheng)
  • Quentin Corradi – Hardware compilation, program analyses, high-level synthesis (primary supervisor: John Wickerson)
