Additional Information:
Teaching Interests
I am interested in teaching at an interface between Chemistry and Biological Sciences. The molecular details afforded by "traditional" chemistry provide great insight into the biological processes that the students seem to be most interested in.
Research Interests
My research interests mirror my teaching interests in that I am investigating biological processes and interactions using analytical, biochemical, and biophysical techniques. One of the main focuses of the lab, currently, is the investigation of initial pathogen/host cell interaction preceding invasion by Shigella ssp.
