B.A. in Chemistry, Drew University
Ph.D. in Chemistry, Massachusetts Institute of Technology

Research Interests
As a biochemistry researcher, I continue to explore the DNA interactions of novel dirhodium compounds with potential anticancer activity. As an educator I am exploring two areas that affect student learning: (1) the impact of guided-inquiry activities on student development of molecular visualization skills in Biochemistry and (2) development of quantitative skill interventions to improve student success in Introductory Chemistry.

Office phone: 610-861-1607

B.S. in Biomedical Science, Lynchburg College
Ph.D. in Chemistry and Biochemistry, University of Delaware

Research Interests
I am interested in understanding how phosphorylation of Gap Junction (GJ) protein, Connexin 43 (Cx43), affects its function. GJs are pores found in plasma membranes of two neighboring cells and are made up of 12 Cx43 molecules. These pores are the only means cells have for direct cell-cell communication, allowing small molecules and ions to move from cell to cell. Cell-cell communication is key for many cellular functions, such as development, proliferation and differentiation. Current projects are focused on using phosphomimetic mutants of Cx43 to study their ability to interact with other protein partners and to affect GJ function.
