Courses:   Contemporary Biology (GBIO 103), Trelawny Learning Community Seminar (BIO 201), Human Uses of Plants (BIO 364), Laboratory in Human Uses of Plants (BIO 365), Plants and Environment (BIO 366), Plant Cell and Tissue Culture (BIO 460/560).

Research Interests:  Propagation of rare and endangered species; Antioxidants in Foods and Beverages.

We use tissue culture and cryopreservation for preserving and propagating members of rare and endangered species. Germplasm conservation is an important part of protecting biodiversity. We also measure the antioxidant content of plant-derived foods and beverages.  Antioxidants are important in the maintenance of good health and as protection against cancer and a variety of human diseases.
