Overview
I am broadly interested in how organisms adapt the their environment at a molecular level. My research is largely focused on conservation genetics in wild populations of marine organisms and my lab employs a combination of molecular, genetic, and genomic tools. My lab is currently working on conservation genetics and hybridization in river herring, populations of juvenile summer flounder using the Pamlico Sound as a nursery, environmental selection of blue crabs in Lake Mattamuskeet, identifying genes involved in barnacle adhesion, and use of environmental DNA to detect anadromous fish and species composition in the ichthyoplankton.
