Riley Mounsdon
South Dakota State University (MS)
Riley is from Osakis, MN and has a B.S. from SDSU in Natural Resource Law Enforcement, Wildlife and Fisheries Science, and Ecology and Environmental Science ('22). Riley's research looks at how managers use fish stocking in South Dakota as well as typifying South Dakota anglers and how they respond to stocking through their license sale purchases. Riley is working to create a framework to assist SDGFP and possibly other agencies with the stocking decision making process.

Katie Bearden
South Dakota State University (MS)
Katie is from Laramie, WY and has a BS in Wildlife and Fisheries Biology and Management ('21). Katie's research focuses on Paddlefish and Walleye movement in the Mississippi River and Lake Oahe, respectively. Specifically, I am using acoustic telemetry data within a multi-state model framework to determine the probability of movement and survival of individual fish.

Maddy Siller
South Dakota State University (MS)
Maddy is from Hutchinson, KS and has a B.S. in Wildlife, Fisheries, Conservation, and Environmental Biology from Kansas State University ('22). Maddy's research examines changes in fish communities related to climate change.
With Dr. Steve Chipps & Dr. David Coulter
Kelsey Crowley
South Dakota State University (MS)
Kelsey is from Peoria, IL and has a BS from Union University in Zoology ('23). Kelsey's research focuses on creating habitat suitability models for endangered and threatened freshwater mussels by using host fish distribution data. The habitat suitability models will be used by agencies in SD, WY, and NE to propagate and survey mussels.

Current Undergraduate Researchers
Lauren Allex
South Dakota State University (BS)
Lauren is from Danube, MN. Lauren's research is examining isotopic niche and diet overlap among three sport fish across different seasons and habitats.

Sarah Hayden
South Dakota State University (BS)
Sarah is an undergraduate wildlife and fisheries science major from Aberdeen, SD. Her research looks at potential causes of walleye movement in response to variations in water level in Lake Kampeska.

Past Postdocs
Peter Pfaff
Peter’s project focuses on modeling inter-basin connectivity during flooding that could facilitate the dispersal of invasive species. Peter is now faculty at St. Mary's University

Past Graduate Students
Jake Bowman
Southern Illinois University (MS)
Jake is now a PhD student at University of Idaho.
Jake's research examines the influence of invasive fish excretion on native aquatic communities.
With Dr. Jim Garvey and Dr. Dave Coulter
Logan Cutler
South Dakota State University (MS)
Logan now works for Wisconsin DNR.
Logan is from Neenah, WI and holds a BS in Fisheries and Aquatic Sciences with Biology and Soil Science minors and a Wetlands certificate from University of Wisconsin - Stevens Point ('21). Logan is researching Walleye use of wetland habitat in Lake Kampeska, SD by collecting diet samples, assessing prey fish communities, and tracking walleye movements between the lake and its wetlands. These data will be used in a bioenergetic framework to assess the energetic importance of these wetlands to adult Walleye in the system.

Miriam Moreno
South Dakota State University (MS)
Miriam is from Yuma, Arizona, and obtained her B.S. in Biology with a concentration in Evolution, Ecological, and Organism Biology ('22). Her research uses ecosystem modeling to illustrate the ecological impacts of bigheaded carp removal. Future implications of this research will help influence bigheaded carp's management decisions. Miriam's research interests include ecology, invasive species, conservation, and management.

Taylor Mongavero
Southern Illinois University (MS 2023)
Taylor's work examines movement patterns of Silver Carp and how this relates to individual condition and morphometrics.
With Dr. Jim Garvey and Dr. Dave Coulter
Andrew Wieland
Southern Illinois University (MS)
Andrew used telemetry data to estimate mortality rates of invasive Silver Carp in areas where they experience contracted removal, commercial harvest, and no harvest or removal. Andrew is currently employed by Illinois Natural History Survey.
