Dr. Ramsey earned his BA from the University of Chicago in 2000 and his PhD in 2004 from Harvard University.  Before coming to DePaul, he spent five years as a Postdoctoral Assistant Professor at the University of Michigan, during three of which he was partially supported by an NSF Postdoctoral Research Fellowship.

Dr. Ramsey's research interests lie primarily in number theory.  Most of his work revolves around p-adic properties of modular forms and modular forms of half-integral weight.  He has also done some work in the area of Euclidean rings and ideals.
