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 a 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.

B.S.c, Queen's University
Ph.D., Queen's University

Research Interests
The focus of my research is on developing separation methods to investigate complex environmental and biological systems. We use liquid and gas chromatography and capillary electrophoresis to explore peptide folding, the distribution and fate of toxins in the environment, and the chemical defenses of insects.
