Laura Ladwig, Ph.D.

Assistant Professor
Department of Biology
University of Wisconsin Oshkosh
Office: 043 Halsey Science Center








  • Ph.D., 2014, Biology, University of New Mexico
  • M.S., 2009, Biology, Eastern Illinois University
  • B.S., 2004, Botany, University of Wisconsin-Madison

Courses Taught

  • BIO105: Biological Concepts – Unity

Research Interests

Dr. Ladwig studies how and why plant species diversity and abundance change, in particular focusing on the impacts of human-caused global factors. She combines experimental, observational, and theoretical approaches to test broad conceptual issues regarding the composition and functioning of ecosystems. Much of her research is focused in grasslands and savannas in the Midwest.
