Biography

I am currently a Professor of Physics at Pacific Lutheran University. My research interests are in the intersection of high energy physics and cosmology. From 2008-2011 I was a postdoctoral researcher in Theoretical High Energy Physics and Cosmology at McGill University. While there, I was a McGill Lorne Trottier and Institute of Particle Physics (IPP) Postdoctoral Fellow.

I obtained my Bachelor of Science in Physics at The Ohio State University in 2003, completing a senior research project entitled “Renormalization of the n-dimensional Delta function potential” under the direction of Professor Robert Perry.

In 2003 I began my graduate study at the University of Wisconsin-Madison, earning a Masters of Arts in Physics in 2005 and a Ph.D. in 2008 as a student of Gary Shiu. My Ph.D. thesis, entitled “Warped String Phenomenology: Topics in Cosmology and Particle Physics”, focused on the interesting phenomenological and cosmological implications of warped extra dimensions, which commonly appear in string theory models.
