Broadly speaking, I am an integrative physiologist interested in the impact of environmental toxicants on crustaceans. As reported by the National Toxicology Program under the US Department of Health and Human Services, over 80,000 chemicals are registered for use in the United States and approximately 2,000 new ones are introduced each year for use by the general public. Many of these compounds appear in water resources long before potential impacts on local species are known. Using an integrative approach allows us to assess the effects of potential toxicants without being tied down to a specific level of organization, experimental technique, or toxicant class. Students in my lab use an ever changing set of experimental tools in their work with DNA, RNA, protein, isolated mitochondria, cultured tissues and whole animals. The organism, level of organization, and tools we use are dictated, first and foremost, by the experimental question at hand. My lab is currently focused on two lines of investigation:
