I was born in King George County, Virginia, and attended the King George public school system. I obtained my BS in Chemistry from Randolph-Macon College in 1997. From there, I traveled to Penn State University in State College, PA, where I obtained my Ph.D. degree in 2001 under the guidance of Dr. Ayusman Sen. I returned to Randolph-Macon College in the summer of 2001 as a faculty member.

- Polymer Chemistry
My research interests lie mainly in the fields of polymers and forensic science. I am especially interested in the synthesis of polymeric materials with interesting physical and chemical properties (such as polynorbornenes and polyacrylates), and the synthesis of the monomers which are the building blocks of these polymers. Recently, I have also become interested in using analytical techniques such as NMR to to determine microstructures of various polymeric materials, as well as to determine adulteration of consumer products.
