Background
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.
Teaching
Fall 2005: General Chemistry Lecture, Analytical Chemistry, Chemistry
and Crime.
J-Term 2006: The Chemistry of Winemaking (We will be travelling
to Napa Valley, San Francisco, and Davis, California).
Spring 2006: Instrumental Chemistry
Research Interests
My research interests lie mainly in the field of polymers. 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.

The R-MC Polymer Characterization
Laboratory
The R-MC Polymer Characterization Laboratory consists of three
main instruments:
A Perkin-Elmer TGA6
A Perkin-Elmer Pyris6 DSC
and a Waters Breeze Size Exclusion Chromatography System
These instruments are used both in my research and in various courses
throughout the department. They are helpful in establishing molecular
weight, thermal stability, and phase transition temperatures for
polymers synthesized at Randolph-Macon. In addition, our JEOL 400
MHz NMR is used extensively in polymer characterization research
and laboratories.
