Postdoctoral researchers

Ranjan Muthukrishnan, 2016-2018 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 research 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. Ranjan is now a Fellow with the Environmental Resilience Institute at Indiana University.

Evelyn Williams, 2015-2017. Evelyn was a postdoc and remains a Co-PI on our project testing the role of phylogenetic diversity in prairie restoration. Her work encompasses plant conservation, genetics, and ecology.
