Research Interests

My group has two broad focus areas: synthetic and mechanistic organic chemistry, and chemical aspects of marine toxins, including isolation and characterization, SAR, sensing, and chemical modification through semisynthesis. In the area of marine toxins, we are focusing on the following projects:

Develop fluorescent sensors for marine toxins using molecular recognition concepts and combinatorial chemistry

Isolate, purify, and characterize new toxins from cyanobacteria
