Dr Trevor JonesDr. Trevor JonesCEO
Trevor has over 15 years experience of devising and managing innovative research and conservation projects in East Africa, with an emphasis on threatened mammals. He first studied elephants in Tsavo, Kenya in 2001, before moving to southern Tanzania. In 2004, while studying endangered primates in the Udzungwa Mountains, he chanced upon kipunji, the first new monkey species to be described in Africa for 25 years.  After completing a thorough census and conservation assessment of the ‘punky monkey’, he embarked on a PhD study of large mammal ecology in the Udzungwa montane forests.  In 2008, having previously documented threatened elephant corridors between Udzungwa and Selous, he led the first national assessment of wildlife corridors across Tanzania. From 2009 to 2010, Trevor also worked with TAWIRI and WCS as senior scientist for the current Tanzanian Elephant Management Plan, a role which included assessing the demography, abundance and conservation status of all Tanzania’s major elephant populations. Trevor has published over thirty papers and numerous reports on African wildlife and conservation.

Emma ImpinkPrograms Manager

Emma has worked in East Africa for more than eight years, mostly on the human side of things. After majoring in African Studies at Barnard College and spending a semester at the Wildlife Management Program at the School for Field Studies in southern Kenya, she returned in 2011 with The BOMA Project as a Princeton in Africa Fellow. There, she conducted the organization’s first impact assessments of small businesses started by micro-grants and provided field support in 18 villages in northern Kenya. At the end of 2012, she moved to Tanzania to help start One Acre Fund’s operations. Over the following 6+ years, she helped grow the organization from serving 1,000 farmers to over 50,000. At One Acre Fund, she built the Monitoring and Evaluation Team, the Product Innovations Department and eventually became Tanzania’s Director of Impact. After supporting the program’s expansion to northern Tanzania and consulting on behavior change work in Burundi, Emma left One Acre Fund and joined STEP. Emma has always been passionate about conservation and human-wildlife coexistence. Rather then seeing STEP as a career shift, she prefers to see it as coming home.
