Dr Trevor JonesDr. Trevor JonesDirector
Trevor has 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.

jenn2Jenipha Mboya  –  Education Officer
Jeni is an enthusiastic conservationist with a BSc in Wildlife Science and Conservation from University of Dar es Salaam, who loves communicating her passions to others and especially young people. She joined STEP in 2015 as Research and Advocacy officer, and she assists with monitoring and research of elephants in Ruaha and Udzungwa, as well as research on human-elephant interactions in southern Tanzania. She is also an advocate for elephant conservation, and has led conservation education and park visitation programs with Iringa secondary schools.

Paulo MndemePaulo MndemeField Assistant
Paulo has worked on the project since its inception in late 2008. Together with Katarzyna Nowak,  Paulo surveyed elephants in several remote forests of the Udzungwa from 2008-10, developing a range of fieldwork skills. He is an expert in counting and examining the contents of elephant dung, and camera trapping of crop raiding bulls. Paulo leads STEP’s elephant protection fence project in Mang’ula.

Joseph KidibuleJoseph KidibuleField Assistant
Joseph also joined the project in late 2008. A farmer himself who has been personally affected by crop-raiding elephants, Joseph loves wilderness fieldwork, whether in moist forest or dry bush. Together with Paulo, he has also worked tirelessly with other local farmers to monitor and mitigate crop damage, and to reduce conflict with elephants – and has become a beekeeper in the process.

kephaKephania Mwaviko – Human-elephant Coexistence Officer
Kepha joined us in December 2016 to carry out monitoring of human-elephant interactions in the Ruaha-Rungwa ecosystem. Kepha is from Makifu village near Ruaha, and qualified as a tour guide at Mkuyu Guiding School in Tungamalenga. He is fulfilling his dream of working with communities to build coexistence with elephants. Kepha is always happiest around a bush television (camp fire), and is constantly increasing his knowledge of birds, trees and all things natural.

In 2008, together with Trevor Jones, she established the Udzungwa Elephant Project (now the Southern Tanzania Elephant Program) and embarked on a survey of elephants in the montane forests of Udzungwa. Her most recent research has focused on how wild primates deal with risk in a “landscape of fear”. She has mentored a number of student projects in Tanzania and elsewhere, and contributes to the scientific research of STEP. She is one of the founders of Request a Woman Scientist, a global directory that aims to improve the visibility and participation of woman scientists across society. She has contributed pieces about wildlife conservation to a variety of popular outlets including online National Geographic, bioGraphic, and Mongabay.

Dr Rocío Pozo – Research Advisor

Rocío has been working in conservation in Africa, Latin America and Europe for over ten years. Her research lies at the interface between the ecological and social aspects of conflicts in conservation that aims to benefit both, local people and wildlife. In particular, Rocío has been working with elephant conservation looking at effective ways to reduce and prevent conflicts between local peoples’ livelihoods and elephant conservation, by successfully developing and implementing crop-loss mitigation methods in Africa.

Dr Pozo is a qualified vet, with an MSc in Conservation (Imperial College London) and a PhD in Zoology (University of Oxford). As one of STEP’s Research Advisors, Rocío provides support for data collection and analysis, and advises on the implementation of conflict mitigation methods in the field. 

Dr. Jeremy Cusack – Research Advisor

Originally from the French Alps, Jeremy moved to the UK to do an undergraduate degree in Zoology at the University of Bristol followed by an MSc in Conservation Science at Imperial College London. He obtained his PhD from the University of Oxford in 2016 and is now a postdoctoral researcher on the ConFooBio project at the University of Stirling.

His primary research interests focus on how conflicts between wildlife conservation and other human activities develop over time. He is also slightly obsessed with camera trapping and spent most of his PhD designing and testing ways of quantifying mammal community patterns and processes from camera trap images taken across the Ruaha landscape in Tanzania. Last but not least, he loves analysing animal movement trajectories collected using GPS collars (or other devices) to investigate habitat-use, species interactions and responses to anthropogenic landscapes.
