Much of my previous research focused on the impact of contaminants on aquatic organisms, particularly the development of resistance in chronically exposed populations. While toxicity mechanisms do fascinate me I am an ecologist at heart. My current research, conducted in colaboration with Dr. Stull and others, focuses on utilizing DNA fragments released by aquatic organisms to establish their presence and abundance in aquatic systems. By targeting specific sequences of mitochondrial genes 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. The utilization of molecular techniques (RT PCR, sequencing, bioinformatics) to efficiently answer ecological questions has great appeal to me.
We recently completed projects using this technique to detect both hellbenders (Cryptobranchus alleganiensis) and local darter species. Current projects include examining temporal fluctuations in eDNA of multiple salamander species and correlations with life history in central KY streams, conducting caging studies to examine eDNA detection limits, and examining the impact of various environmental parameters on eDNA release and persistence.
