I am associate professor of mathematics at Lock Haven University of Pennsylvania, one of the fourteen universities in the Pennsylvania State System of Higher Education.  I am also the book reviews editor for Dynamical Systems Magazine, the on-line publication of the Dynamical Systems Activity Group of the Society for Industrial and Applied Mathematics (SIAM).

I earned my B.A. in mathematics at the University of Louisville in 1995, my M.S. in mathematics at Michigan State University in 1998, and my Ph.D. in mathematics at Michigan State University in August 2003.

In my Ph.D. thesis, I studied the decay of correlations of piecewise smooth hyperbolic dynamical systems for which the distortion on unstable manifolds is not uniformly bounded. I am currently working on stability questions in functional equations.

For a more detailed description of my research, please see my research statement.

The full text of my Ph.D. thesis will be available on-line soon. In the meantime, I will be happy to send you a copy by e-mail or "snail" mail. If you would like a copy, send me an e-mail.

My bachelor's thesis studied a generalized result of the well-known Hyers-Ulam question on approximate homomorphisms. The full text of my bachelor's thesis is found here.  You can read a bit more about it on Jeux et Mathématiques.
