Research Interests:

My research in the Kubanek Laboratory investigates the specialized metabolites of a noxious marine alga. The goals of this project are twofold: (1) to determine whether algal molecules have potential medicinal application and (2) to understand the ecological impacts of these compounds on marine ecosystems. Prior to joining the Kubanek Lab, I completed my Ph.D. under Dr. Lena Gerwick at Scripps Institution of Oceanography where I elucidated the mechanism of action of honaucin A, a cyanobacterial natural product with anti-inflammatory activity.
