My research focuses on certain mathematical objects known as Shimura varieties. Shimura varieties arise in many guises, but they may be most familiar as the parameter spaces of abelian varieties. Abelian varieties are central objects in number theory — the simplest abelian varieties, known as elliptic curves, are now at the heart of modern cryptography. For this reason, and others, questions regarding the geometry of Shimura varieties can inspire and illuminate many questions in number theory and beyond.
