J.J. Sylvester Assistant Professor
Johns Hopkins University

PhD, University College London, 2024
MMath, University of Warwick, 2020

My research is broadly in the area of geometric analysis, using techniques from the calculus of variations, geometric measure theory, and partial differential equations.

I am on the job market for positions starting Fall 2027.
