I am a PhD candidate in the Operations Research & Financial Engineering (ORFE) department at Princeton University, where my research interests include mathematical statistics and probability theory. Currently I am working with my advisor Matias Cattaneo on nonparametric network estimation, martingale coupling theory and random forest procedures.

In July I will be joining the Statistical Laboratory in the University of Cambridge Department of Pure Mathematics and Mathematical Statistics as a postdoctoral researcher hosted by Richard Samworth.


I received an MA degree in ORFE from Princeton in 2021. Before moving to New Jersey, I obtained my MMath in Mathematics & Statistics from the Department of Statistics at the University of Oxford in 2019. I was supervised there by Mihai Cucuringu, and wrote my master’s dissertation on Motif-Based Spectral Clustering of Weighted Directed Networks. I am an alumnus of St John’s College, Oxford.

In my spare time I enjoy choral singing, classical piano, chess and programming, as well as hiking, skiing and playing squash.
