I am a professor in the Department of Mathematics at Penn State. I am interested in number theory, arithmetic geometry, and applications to cryptography. My research is currently supported by a grant from the Department of the Army, and an NSF grant. In 2008 I was awarded a Sloan Research Fellowship, and in 2011 an NSF CAREER award. There are currently four Ph.D. students working with me.
