I am currently a DPhil student in mathematics at the University of Oxford, supervised by prof Ben Green. My main research interests lie in additive combinatorics, number theory and harmonic analysis.
I am also a Lecturer I at Magdalen College, Oxford. I did my BA and MMath at St John’s College, Oxford and I wrote my master's thesis 'On zero density estimates' under the supervision of James Maynard in 2021.
I'm starting a postdoc with prof Julian Sahasrabudhe in Cambridge in October 2025.
