Brian Conrad

Brian Conrad (born November 20, 1970), is an American mathematician and number theorist, working at Stanford University. Previously he taught at the University of Michigan and at Columbia University.
Conrad and others proved the modularity theorem, also known as the Taniyama-Shimura Conjecture. He proved this in 1999 with Christophe Breuil, Fred Diamond and Richard Taylor, while holding a joint postdoctoral position at Harvard University and the Institute for Advanced Study in Princeton, New Jersey.
Conrad got his bachelor's degree from Harvard in 1992, where he won a prize for his undergraduate thesis. He did his doctoral work under Andrew Wiles. He received his Ph.D. from Princeton University in 1996 with a dissertation entitled Finite Honda Systems And Supersingular Elliptic Curves. He was also featured as an extra in Nova's The Proof.
His identical twin brother Keith Conrad, also a number theorist, is a professor at the University of Connecticut.
