Postdoctoral researchers

Ranjan Muthukrishnan, Ph.D. Ranjan's research focuses on integrating empirical and theoretical approaches to understand the dynamics of major shifts in ecological communities. This has included working in coral reef communities to evaluate how anthropogenic stresses can drive shifts between coral-dominated and algal-dominated community states and more recent work on biological invasions focusing on the properties that make communities susceptible to invasive species and the community consequences of the displacement of native foundation species.








Jesús Pinto Ledezma, Ph.D. Jesús is from the lowland region of Bolivia and his research focuses on the intersection between macroevolution and macroecology. He applies macroevolutionary theory and phylogenetic comparative methods to understand geographic patterns of species diversity and the assembly of local biotic communities. Also, as a field biologist, he loves to explore all aspects of the natural history of vertebrate species, especially Neotropical birds. Jesús is co-advised by Dan with Jeannine Cavender-Bares.



Research staff

Wesley Glisson. Wes is a Research Fellow involved in many aspects of our field and laboratory research. For his M.S. with Dan at Northwestern University, Wes investigated the sensitivity of secretive marshbirds to vegetation condition in natural and restored wetlands in southern Wisconsin. Before coming to UMN, Wes worked as a researcher in plant biology at Chicago Botanic Garden and in wildlife biology at the USGS Coop Unit at the University of Idaho.










Graduate students

Rafael Contreras-Rangel. Rafa is a Master's student in Conservation Sciences whose work addresses management of the invasive green alga Nitellopsis obtusa (starry stonewort).



Michael Verhoeven. Mike is a PhD student in Conservation Sciences conducting research on ecology and management of aquatic invasive plants. The focus of his current research is quantifying the effects that invasive aquatic plants have on native ecosystems and examining the mechanisms of their reproduction and colonization.








Carli Wagner. Carli is a Master's student in Conservation Sciences whose work addresses plant-community impacts of the invasive green alga Nitellopsis obtusa (starry stonewort).
