Research & Teaching

My research and teaching interests lie at the intersection of organic chemistry and biology.  I enjoy collaborating with undergraduate students in the classroom and laboratory to understand how nature drives chemical innovation, and how humans can leverage this information to discover environmentally responsible routes to novel therapeutic agents. 

Funding

I'm very grateful to the following funding agencies for believing in our work: National Institutes of Health (R15), National Science Foundation (CAREER and RCN), and Research Corporation for Science Advancement (Cottrell Scholars Award and Cottrell College Science Award).
