Biogeochemistry Laboratory (LBL)

I am an ecosystem scientist who works at the interface of ecology, earth system science, and hydrology studying the processes shaping ecosystems and their responses to anthropogenic changes. From this foundation, I tackle the challenges and complexities of sustainability and global change science. My primary research interests include 1) understanding the hydrologic and biogeochemical processes shaping watershed ecosystems, 2) studying the ways in which land use and other human-caused changes are altering these processes in both terrestrial and aquatic ecosystems and across these traditional disciplinary boundaries, and 3) integrating social processes and other human dimensions into watershed and ecosystem management.

Biographical Sketch

Dr. Lohse has been a Professor at Idaho State University since 2019 and shares a joint appointment with the Department of Geosciences. She obtained her Ph.D. from UC Berkeley in 2002 working with Pamela Matson at Stanford University and Ronald Amundson at UC Berkeley. Her training was in soil science with an emphasis in ecosystem ecology/soil biogeochemistry. Prior to her employment at ISU in 2010, Dr. Lohse worked at University of Arizona for three and half years as an Assistant Professor.
