I am a Turing Research Fellow in Mathematics at Oxford. Until recently, I was a postdoc at Penn and a PhD candidate at Rutgers. Here is a brief CV, and here are my profile pages on MathOverflow, on Google scholar, and on LinkedIn.
I develop theories, algorithms and software for algebraic-topological analysis of large datasets which arise from simulations or measurements made in a variety of contexts. Here is a brief research statement (pdf alert), here are some papers, and here's the Perseus homology software.
I am not teaching this semester. For information on courses that I've taught previously, see the teaching page.
