Teaching Interests

I am Interested in all levels and aspects of science education: At the undergraduate level, I teach introductory biology, biochemistry, and biochemistry laboratory. At the graduate level, I teach photobiology, current literature topics, and teacher education courses. Included in all of these courses is a healthy input of multimedia assisted presentation programs and computer-assisted interactive tutorials which we have developed. Research and teaching interest overlap with the development of research grade environmental monitors Director of Premedical Studies and Health-Related Careers Program, and Director of Teacher Certification Program for students in Biology.

Research Interests

Research is centered on an experimental approach to biochemical reactions and environmental perturbations. The biochemical studies involve the use of instrumentation to analyze plant protein complexes. The environmental monitoring work is centered on measuring anthropogenic inputs on water systems, such as acid precipitation on freshwater ponds and pools in Massachusetts. Environmental monitoring includes development of on-site instrumentation to monitor pH, temperature, and oxygen concentration, and also the collection and analysis of freshwater organisms. Recently, this has involved the use of stable isotope analysis of organisms in the water systems to determine structure of food webs and possible effects of anthropogenic inputs.
