Current Postdocs and Graduate Students

Cait Rottler, PhD student. Cait is studying the interactions of soil carbon and nitrogen, and vegetation communities, with the history and practices of reclamation on well pads in Wyoming. 

Christopher Beltz, PhD Student

Christopher Beltz, PhD student (2014 - present).

Chris ( is studying plant-soil interactions and nutrient cycling at the ecosystem and community level using an approach that incorporates biogeochemistry, soil science, ecosystem ecology, and soil microbiology.  He is currently working on a project in Pinedale, WY examining the effects of nitrogen fertilization on sagebrush plant communities.  He hopes to further elucidate the role of nitrogen in sagebrush communities, which is complex due to the co-limitation by both nitrogen and water availability.  This study also has implications for the management of mule deer near natural gas development, as large areas of sagebrush were recently fertilized by Wyoming Game and Fish in order to improve mule deer habitat.
