My interests lie in the ecology, biology, systematics, population genetics, and zoogeography of fishes. I currently work with the USGS Nonindigenous Aquatic Species Database program helping to refine our understanding of nonnative fish distributions and impacts in the United States.

READI-Net: A network of robotic environmental DNA samplers to enhance the early detection of aquatic biological threats
USGS researchers are working with the Monterey Bay Aquarium Research Institute to optimize autonomous, robotic samplers for detection of DNA fragments shed by biological threats (BT; invasive species, parasites, pathogens) in our nation’s waters. Finding DNA fragments (a method known as environmental DNA sampling) produced by an emerging BT in water is akin to finding a needle in a haystack—many...
Implementing FAIR practices: Storing and displaying eDNA data in the USGS Nonindigenous Aquatic Species database
We are working to incorporate environmental DNA (eDNA) data into the Nonindigenous Aquatic Species (NAS) database, which houses over 570,000 records of nonindigenous species nationally, and already is used by a broad user-base of managers and researchers regularly for invasive species monitoring. eDNA studies have allowed for the identification and biosurveillance of numerous invasive and threaten
Establishing standards and integrating environmental DNA (eDNA) data into the USGS Nonindigenous Aquatic Species database
Environmental DNA (eDNA) testing allows for high sensitivity monitoring efforts of cryptic species in large, remote systems and is performed by investigating water and soil samples for sloughed DNA. Having access to eDNA datasets across multiple taxa and ecosystems is necessary for improved coordination among researchers and management. Additionally, quality control protocols are needed to vet inc
National Public Screening Tool for Invasive and Non-native Aquatic Species Data
Identifying the leading edge of a biological invasion can be difficult. Many management and research entities have biological samples or surveys that may unknowingly contain data on nonindigenous species. The new Nonindigenous Aquatic Species (NAS) Database automated online tool “SEINeD” (Screen and Evaluate Invasive and Non-native Data) will allow a user to search for these nonindigenous occurren...
The Nonindigenous Aquatic Species Alert Risk Mapper (ARM)
The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.
Defining Native Ranges of U.S. Inland Fishes
Understanding the native versus non-native range of a species can provide useful information about dispersal, population distribution patterns, and human mediated movement across hydrologic barriers. The USGS Nonindigenous Aquatic Species (NAS) Program is working with partners to define native ranges of inland fishes in the United States to help identify which species should be included in the NAS...
The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
Knowledge Extraction Algorithms (KEA): Turning Literature Into Data
Identifying, extracting, and mobilizing information from current and historical literature is a time-consuming part of organizing and collating synthetic data productions. This project explored the use of algorithm-based methods to identify and extract occurrence information from the GeoDeepDive (GDD) literature database to support upkeep of the Nonindigenous Aquatic Species (NAS) data. The GeoDee
National Alert Risk Mapper for Nonindigenous Aquatic Species
The Nonindigenous Aquatic Species (NAS) Database and Alert System (https://nas.er.usgs.gov/default.aspx) provides a framework for the rapid dissemination of new invasions as they are incorporated into the NAS Database. The system notifies registered users of new sightings of >1,330 non-native aquatic species as part of national-scale early detection and rapid response systems (EDRR), and in suppor
Great Lakes Aquatic Nuisance Species Information System
The Great Lakes Aquatic Nuisance Species Information System (GLANSIS) was developed by the NOAA Great Lakes Science Center to monitor nonindigenous aquatic species introductions into the Great Lakes region.
Nonindigenous Aquatic Species (NAS) Program
Welcome to the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. Located at Gainesville, Florida, this site has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, distribution maps, and general...
Nonindigenous Aquatic Species Database and Website (NAS)
Nonindigenous - non-native - species threaten biodiversity, but the distribution of these species is not well-known. The Nonindigenous Aquatic Species (NAS) database tracks occurrence data on non-native aquatic plant and animal species throughout the United States, and provides the public with species profiles, distribution maps, and online/real-time queries for state/hydrologic basin- specific...
