- Intended Degree:
- Ph.D., Marine Biology and Fisheries
My research interests are in the areas of evolutionary physiology and environmental toxicology. I have conducted a wide range of studies investigating the effects of metals on freshwater and marine organisms and am currently study the effects of Cu and Pb on the freshwater pulmonate snail, Lymnaea stagnalis and the effects of dietary silver exposure on marine invertebrates. My Ph.D. research is focused on evolutionary physiology of the pupfish Cyprinodon variegatus. I am currently investigating differences in ionoregulatory capacity between the coastal form (C. v. variegatus) and a derived inland lake form (C. v. hubbsi) of this fish. C. v. hubbsi has been isolated in several lakes in central Florida for the past ~200,000 years. My research has shown this inland lake form has evolved an ability to acquire Na+ at significantly lower (~two orders of magnitude) ambient Na+ concentrations than the coastal form. I’ll be investigating the specific transport mechanisms involved in these observed differences and the molecular evolutionary processes that led to these changes.
