研究领域

Professor Witt's research is focused on the application of molecular markers to address questions related to the ecology and evolution of aquatic organisms. A central theme that is currently being addressed in Professor Witt's lab concerns the reasons for, and consequences of disparities between rates of evolution at the molecular and morphological levels. To address these issues, we employ both population and species level comparative approaches. The lab is also engaged in research related to conservation, toxicology and the use of molecular methods for the diagnosis of species boundaries.
