AIS Area of Interest
Dr. Larkin specializes in aquatic and wetland plant management and restoration. His research addresses applied problems concerning how to reduce the spread and impacts of invasive plant species and support the recovery of impacted areas through ecological restoration and management. His work with MAISRC involves research and extension outreach on risk assessment, control, and post-treatment restoration of aquatic habitats impacted by Eurasian watermilfoil, curly-leaf pondweed, non-native Phragmites, starry stonewort, and other invasive plants.

Julia Bohnen has a B.S. from the University of Wisconsin- River Falls and an M.S. from the University of Minnesota. She is involved in both research and teaching related to ecological restoration and invasive species management. Julia’s current research seeks to engage professionals and volunteers throughout Minnesota in identifying and reporting locations of the European haplotype of Phragmites australis (common reed) to understand its likelihood to spread and its potential to impair ecological functions. Previous projects include a restoration evaluation research project that sought to assess the outcomes of ecological restorations funded by the Environment and Natural Resource Trust Fund. She helped develop a series of online ecological restoration courses that are currently offered through the College of Continuing Education. She has 14 years of project management experience from the Minnesota Landscape Arboretum, where she was responsible for restoring and monitoring Spring Peeper Meadow, a landscape scale ecological restoration.
Rafael Contreras-Rangel is a Master's student in the Conservation Science with a focus on Fisheries and Aquatic Biology. He graduated from Kenyon College with a BA in biology and a concentration in environmental studies. After graduating I started becoming interested in invasive species while doing restoration work for the Natural Area Preservation Division of the City of Ann Arbor. Having been a swimmer my whole life, I moved to Minnesota with the hope of transitioning from doing conservation work in a terrestrial system to an aquatic one. While working as an Aquatic Invasive Species Specialist for the Conservation Corps of Minnesota & Iowa, I became interested in starry stonewort ecology and management. My research focus will be studying the efficacy of chemical control on starry stonewort in a lab setting.
Wes Glisson is a research fellow in Dr. Larkin’s Lab. He received a B.S. in Biological Sciences from Northern Illinois University and a M.S. in Plant Biology and Conservation from Northwestern University. His work focuses on understanding the ecology of aquatic invasive plant species within an applied management and restoration framework. His current research projects include examining the mechanisms and impacts of starry stonewort (Nitellopsis obtusa) invasion, and understanding the relative invasive ability of Eurasian versus hybrid watermilfoil (Myriophyllum spp.).
Laura Dee is an assistant professor in the Department of Fisheries, Wildlife, and Conservation Biology and is a partner on the Phragmites project.
Ranjan Muthukrishnan is a Postdoctoral Research Associate whose interest is in the basic ecology of invasions including factors that make a community susceptible to invasions and the ecological consequences of invasions. He also uses a combination of field studies and computational approaches to study complex ecological systems.
Mike Verhoeven is a graduate student working towards a Ph.D. in Conservation Science with a focus on Fisheries and Aquatic Biology. His research focuses on ecology and management of aquatic invasive plants. The focus of his current project is evaluating the factors that influence reproduction and colonization in submerged plant communities following management actions. His work utilizes observational datasets collected during herbicide-based aquatic plant management in the state of Minnesota.
Carli Wagner is an M.S. student pursuing a degree in Fisheries and Aquatic Biology. She is an alum of the Fisheries, Wildlife, and Conservation Biology program at the University of Minnesota. She aims to fill key knowledge gaps on the ecology of starry stonewort. The major focuses of her research include characterizing starry stonewort’s phenology, quantifying impacts of its invasion on native plant communities, and identifying environmental factors associated with nuisance growth.
