William Hagar is interested in all levels and aspects of science education: At the undergraduate level, he currently teaches a freshman seminar course each year, and depending on the academic schedule, teaches Introductory Biology, Biochemistry, and Biochemistry Laboratory. At the graduate level, he teaches 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. His research and teaching interest overlap with the development of research grade environmental monitors. He is the director of the Premedical Studies and Health-Related Careers Program.
Hagar's 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. They use techniques such as stable isotope composition of organisms to determine structure of food webs and possible effects of anthropogenic inputs. His laboratory group also is developing methods to measure methyl mercury in fish tissue using an enzyme-based analysis.
