Research Interests

We are interested in studying the mechanisms by which absorption of electromagnetic radiation by topically applied medicinal compounds may lead to the development of erythema, and in the worst case scenario, skin cancer. Our approach begins by studying the basic photophysical properties of these compounds, their photochemical reactions, and reactive intermediates formed in solution, micelles, and cell lines. We are also interested in developing new pedagogies and course material that may help students develop knowledge of basic chemical principles and their relevance to our society.
