About

I am a PhD student at University of Cambridge working with Dhruv Ranganathan. I'm affliated to Trinity College and supported by the Cambridge Trust.

CV (updated Dec 2024)

Research

I think about moduli spaces in algebraic geometry, their topology, and how they interact with logarithmic and tropical geometry. I also have interests in enumerative geometry.

The $S_{n}$ -equivariant Euler characteristics of $ℳ_{1, n} (ℙ^{r}, d)$ joint with Siddarth Kannan [arxiv].

The dual complex of $ℳ_{1, n} (ℙ^{r}, d)$ via the geometry of the Vakil--Zinger moduli space, joint with Siddarth Kannan [arxiv]. Submitted.

When I'm (not) doing maths I like to listen to music. A few groups I follow and feel close to: Dolphy Kick Bebop (prog, improv), Gong Gong Gong ('phantom rhythm,' in their own words), Mong Tong (pysch, Southeast Asian mysticism), Pu Poo Platter, and Sleeping Dogs (both soul, groove, Afrobeat).
