Graduate PhD opportunity:
One PhD research assistant position is available (beginning Aug. 2018) for a student interested in the
effects of anthropogenic chemicals on ecosystem function. The student will work in the laboratories of
Dr. Lora Perkins and Dr. A. Joshua Leffler in the Department of Natural Resource Management at South
Dakota State University.
The research will focus on the impact of parasiticides used in livestock production on dung beetle
populations, nitrogen cycling, and subsequent forage production. The field component of the research
will be conducted at Ft. Pierre National Grasslands in central South Dakota. The student is expected to
contribute to the broader project, but also develop related research of their own. The student will also
work closely with a PhD student in Rural Sociology to investigate the decision making process of
livestock producers to use or not to use parasiticides. The assistantship includes a stipend and tuition
waiver, and is available for four years contingent on satisfactory progress toward the PhD degree. This
research is funded by USDA-NIFA.
To apply, send as a single PDF document your CV; unofficial transcripts; a letter describing your
experience, research interests, and career goals; and contact information for three professional
