Currently, my research is focusing on three broad areas:

1) The effects of contaminants on aquatic organisms across different levels of biological organization- in particular how organisms tolerate contaminant-induced stress and in the proximate mechanisms that lead to stress responses at the level of the whole animal and ultimately in populations and communities. This work includes studies with microcrustaceans, macroinvertebrates and amphibians.

2) Study of the population dynamics of the invasive zebra mussel (Dreissena polymorpha) in Oklahoma, including how the condition of zebra mussels varies throughout the year and the interactions the mussels have with other aquatic organisms.

3) Use of indicator species (macroinvertebrates, amphibians, plants) to evaluate the condition of depressional wetlands in Oklahoma.
