Research

My lab’s research uses a combination of molecular and field techniques to address ecological questions. Our current work primarily focuses on questions related to the use of environmental DNA (eDNA) in the detection of species, particularly cryptic species, of amphibians and fish. This technique utilizes DNA fragments released by aquatic organisms to establish their presence, and in some cases abundance, in aquatic systems.  By targeting specific mitochondrial sequences we are able to distinguish species based on the DNA they leave behind, enabling us to find the proverbial “needle in a haystack;” organisms that would otherwise be difficult or impossible to detect.
