About

I’m a Sherman Fairchild postdoc at Caltech interested in quantum machine learning and hybrid quantum-classical algorithms. I’ve thought a lot about how to design provably efficient and expressive quantum machine learning models, showing they’re great at solving certain kinds of problems (and not so great at solving even more kinds of problems).

Check out my CV if you want to see more details on some of my highlighted work or just more details about me in general.
