G'day and welcome to my webpage!
I am a mathematical physicist, and from July, London Mathematical Society Early Career Research Fellow based at the University of Sheffield, mentored by Tom Bridgeland.
My current research programme studies geometric structures on spaces of Bridgeland stability conditions. I also often work in conformal geometry and related structures. My perspectives and approaches are usually somehow informed by Roger Penrose's twistor theory.
I am based at Clare College, Cambridge (pictured above), and DAMTP for my PhD studies, supervised by Maciej Dunajski. Earlier, I did Part III of the Cambridge Mathematical Tripos and completed an MPhil with Mike Eastwood at the University of Adelaide.
