E. CURRENT RESEARCH ACTIVITIES AT DICKINSON
During Spring 2001, I will have two students working in my laboratory who are declared chemistry and biochemistry majors. The projects we are currently working on involve the study of how metal limitation affects the biomolecules that are produced in aquatic systems by algae and bacteria. Specifically we are interested in determining how iron limitation affects biomolecule production. There is a great deal of interest in understanding the ocean's role in absorbing excess carbon dioxide from the atmosphere, and one parameter that affects this process is the amount of iron present. In conjunction with researchers at the College of Marine Studies (University of Delaware) and the Department of Chemistry (Penn State), we have been studying the types of biomolecules that are produced which regulate Fe availability to bacteria, as well as how the lack of Fe affects the quality and quantity of carbohydrates that are produced. The goal of these studies is to understand how the structure of these biomolecules affects metal reactivity. This work has received funding from both the Research and Development Committee of Dickinson College, and a Cottrell College Science Award from the Research Corporation. Results from this work have been presented in poster format at the American Chemical Society Meeting in Washington, DC (August 2000) and will be presented in an invited oral presentation at the American Society of Limnology and Oceanography in Alburquerque, NM in February 2001.
