I'm a research fish biologist with interests in fish movement and passage, invasive species management and ecology, and freshwater food web dynamics.
Originally from the U.P. of Michigan, I've always been interested in fisheries and freshwater; however, my interests center around the impacts of invasive species on freshwater ecosystems. I have experience working on ecosystem models and aquatic food webs, particularly related to the impacts of invasive fishes. For the past five years, I've conducted research on the movement dynamics of invasive Asian carps, both with Southern Illinois University (postdoc) and with the USGS, here in La Crosse, Wisconsin. I joined the USGS in 2015 and am currently responsible for conducting research related to movement dynamics of invasive Asian carps in the Illinois River and conducting all studies related to the use of underwater sound to deter invasive fishes in collaboration with the USACE-ERDC, USGS-CERC, and University of Minnesota-Duluth.
Science and Products
Database and web application for invasive carp telemetry data (FishTracks)
Four types of invasive carp fish species, are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade. To prevent the spread of invasive carp into the Great Lakes, the multi-agency Asian Carp Regional Coordinating Committee (ACRCC)...
Invasive Carp Integrated Control and Containment: Acoustic Deterrents for Invasive Carp
The long-term goal of this project is to develop acoustic deterrents to prevent the upstream migration of Invasive carp to the Great Lakes.
Assessment of Acoustic Stimuli for Manipulating Movement of Bigheaded Carps
Invasive Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis, hereafter referred to as bigheaded carps, have displayed a negative phonotactic response when presented with a broadband acoustic stimulus. Additional study is needed to identify effective acoustic stimuli for manipulating bigheaded carp behavior, and to test bigheaded carp responses to those stimuli in...
Assessment of newly developed acoustic stimuli for manipulating movement of bigheaded carps
Bigheaded carps, like other cyprinids, have specialized structures known as Weberian ossicles that increase their hearing range and sensitivity. Recent results from controlled laboratory studies have indicated that playback of a recording of an outboard boat motor was effective at altering silver and bighead carp behavior.
Bioacoustic manipulation of invasive Bigheaded carp
Bigheaded carp, especially silver (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), are invasive fish species that have established breeding populations dominating large regions of the Mississippi Drainage in the 20 years following escape from aquaculture facilities in Arkansas
Application of broadband sound for bigheaded carp deterrence
Bigheaded carp, especially silver (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), are invasive fish species that have established breeding populations dominating large regions of the Mississippi Drainage in the 20 years following escape from aquaculture facilities in Arkansas.
