About

I am an assistant professor in the Department of Mathematics at UWEC. I am an MAA Project NExT fellow and a Math Alliance mentor. You can see my full Curriculum Vitae here. When I'm not doing math, I enjoy rock climbing, hiking, and painting.

Previously, I was a postdoc in electrical engineering at the New Jersey Institute of Technology and Arizona State University, working with Dr. Jörg Kliewer and Dr. Oliver Kosut. I earned my Ph.D. in mathematics at the University of Nebraska - Lincoln (UNL), working with Dr. Christine A. Kelley. I earned my B.A. in mathematics from Whitman College, and my M.S. in mathematics from UNL.

  • Calculus I (Summer 2013, Fall 2013)

Research

My research interests are in error-correcting codes, secure and authentic communication, information privacy, graph-based codes and decoding algorithms, and applied discrete mathematics. If you are a UWEC student interested in doing a research project with me, please get in touch!
