Research Background and Interests
My research background is primarily in molecular ecology. Early projects as a laboratory technician at the Savannah River Ecology Lab included developing microsatellite loci for a Peromyscus genome mapping project and using microsatellites to estimate the frequency of multiple paternity in alligators. My dissertation research at the University of Georgia focused on investigating the relationships between species and genetic diversity of pond-breeding amphibian communities, and the association between these scales of diversity and surrounding landscape features.
Since joining USGS, my research interests have pivoted to the use environmental DNA for detecting species of interest. Projects have included screening isolated wetlands throughout the southeastern U.S. for imperiled pond-breeding amphibians, comparing results between traditional fish and invertebrate survey methods with eDNA metabarcoding methods, and determining sources of fecal contamination in National Park waterways in the southeastern U.S.

Status: Active Actual evapotranspiration, flash droughts, water deficits, reduced vegetative growth, and wildfires: the effects of seasonally water-limited conditions in a changing climate
The Southeastern U.S. experiences recurring hydrologic droughts, which can reduce water availability for human consumption and ecosystem services, leading to plant stress and reduced plant growth. This project examines relationships between drought and the water cycle in the Southeast with data from the Panola Mountain Research Watershed (PMRW) near Atlanta, Georgia and other Southeastern...

Status: Completed Environmental DNA (eDNA)
Environmental DNA (eDNA) is organismal DNA that can be found in the environment. Environmental DNA originates from cellular material shed by organisms (via skin, excrement, etc.) into aquatic or terrestrial environments that can be sampled and monitored using new molecular methods. Such methodology is important for the early detection of invasive species as well as the detection of rare and...

Feral swine as sources of fecal contamination in recreational waters
Recreational waters are primary attractions at many national and state parks where feral swine populations are established, and thus are possible hotspots for visitor exposure to feral swine contaminants. Microbial source tracking (MST) was used to determine spatial and temporal patterns of fecal contamination in Congaree National Park (CONG) in...

Microbial and viral indicators of pathogens and human health risks from recreational exposure to waters impaired by fecal contamination
Fecal indicator bacteria (FIB) (e.g., fecal coliforms, Escherichia coli, and enterococci) have been used for decades to monitor for and protect the public from waterborne pathogens from fecal contamination. However, FIB may not perform well at predicting the presence of waterborne pathogens or human health outcomes from recreational...

Microbial source tracking (MST) in Chattahoochee River National Recreation Area: Seasonal and precipitation trends in MST marker concentrations, and associations with E. coli levels, pathogenic marker presence, and land use
Escherichia coli levels in recreational waters are often used to predict when fecal-associated pathogen levels are a human health risk. The reach of the Chattahoochee River that flows through the Chattahoochee River National Recreation Area (CRNRA), located in the Atlanta-metropolitan area, is a popular recreation area that frequently exceeds...

Adapterama II: Universal amplicon sequencing on Illumina platforms (TaggiMatrix)
Next-generation sequencing (NGS) of amplicons is used in a wide variety of contexts. In many cases, NGS amplicon sequencing remains overly expensive and inflexible, with library preparation strategies relying upon the fusion of locus-specific primers to full-length adapter sequences with a single identifying sequence or ligating adapters onto PCR...
