Collaborative / Interdisciplinary Efforts
I am currently collaborating with Dr. Steve Kaattari (VIMS) and Dr. Erin Bromage (U Mass) on the production of antibody-based biosensors for the quantification of aquatic contaminants in environmental samples. VIMS graduate student Candace Spier is working with us and focusing her dissertation research on the development of antibody biosensors for detection of small aromatic hydrocarbons, as they are important compounds found in the water-soluble fractions derived from oil.
