Public Education

  • Lead organizer of the Jackson Hole Wildlife Symposium, December 2014 (>150 participants)
  • Developed interactive educational materials on wildlife-vehicle collisions for display at the National Museum of Wildlife Art and for Teton Science Schools programs, which collectively reach >12,000 participants each year
  • Founded and edited (2 years) the Mpala Memos newsletter of the Mpala Research Centre, for local stakeholders
  • Authored 12 popular articles for stakeholders and the public in Kenya
  • Numerous public presentations of research in Kenya and Wyoming

Partnerships With Land Managers

  • Work closely with the Wyoming Department of Transportation and Wyoming Game and Fish Department on design, analysis, and interpretation of multiple studies on wildlife-vehicle collisions and mitigations aimed at reducing the negative effects of roads on ungulates.
  • Regularly advise Teton County Planning department on issues of roads and wildlife
  • In collaboration with several NGOs and with funding from USAID, developed methods for simple, quantitative monitoring of rangeland health in East Africa
  • Authored the guidebook Monitoring Rangeland Health: A Guide for Pastoralist Communities and Other Land Managers in Eastern Africa (published by USAID)
  • These monitoring methods now being used by organizations with a footprint of 35,000 km2 in Kenya and Namibia
  • Have led numerous outreach workshops in Kenya and Ethiopia on rangeland monitoring

Teaching and Capacity-Building

  • Fellowship Coordinator, Wyoming Chapter of The Wildlife Society’s fellowship program (2014-2015)
  • Mentored 8 students/interns (B.A.; 2 B.Sc.; 3 M.Sc.; 1 Ph.D.; senior thesis), 2008-2014.
  • Instructor, ECOL 5620: Conservation and Management of Grazing Systems, University of Wyoming, Fall 2012.
  • Instructor, EEB 320: Ecology and Conservation of African Landscapes, Princeton University, Spring semesters 2009-2012.
  • Serve as an affiliate faculty member at the University of Nairobi’s Department of Land Resource Management and Technology.
  • Through this partnership, have supported, trained, and mentored six Kenyan post-bachelors and one post-masters students. All have gone on to more permanent employment or further study.
  • Have also supported three groups of undergraduates (~40 each) from the University of Nairobi to visit field sites and research projects. Without such support, Kenyan students have very little exposure to field research.
