My research interests include aquatic ecosystems, endangered species, and the interrelationship between science and policy for the management of natural resources. I would like to focus a portion of my dissertation work on examining preserved museum specimens to evaluate changes in aquatic ecosystems. This can be accomplished by examining gut contents and measuring stable isotope concentrations of preserved fish, and comparing the results with current food webs to evaluate changes in ecosystems.
