Alan Dumezweni Nare
Alan is an Oppenheimer Impact Scholar and former Masters Scholar with OPALS. He works at Shangani Holistic Ranch, where he supports our bush management experiments and leads spatial analyses of herbivory intensity, vegetation change, and land management interventions. Previously, his Masters research with OPALS focused on the sustainable use of rangelands using drone-based Structure-from-Motion photogrammetry.

Minda Cossa
Minda was an Oppenheimer Impact Scholar in OPALS, researching the role of urban planning in improving resilience to adapt to climate-related coastal hazards in Mozambique, engaging with planning and development practitioners in the community. She undertook an MSc in Global Sustainability Solutions at the University of Exeter before continuing as a Research Associate for 12-months to maximise the impact of her work (video). She was supervised by Dr Andy Cunliffe, Dr Ricardo Safra de Campos, and Dr Gina Ziervogel.
Minda proceeded to a job as a Teaching Assistant at Eduardo Mondlane University, passing on her new skills and insights to amplify the positive impact on her training on others in Mozambique.

Isaac Mureithi
Isaac is an Oppenheimer Impact Scholar working to help develop better models of Conservation Governance, working in the OPALS programme in the close partnership with the African Wildlife Foundation to support their objectives. Coming from a background in actuarial science, Isaac is undertaking an MSc in Conservation and Biodiversity at University of Exeter to expand his conservation knowledge before commencing a 12-month targeted placement at AWF’s Field Office in the Tsavo Landscape. Isaac is supervised by Dr Andrew Cunliffe, Dr Philip Muruthi, Dr Tom Powell, and Dr Kimberley Hockings.

Guy Lomax
Guy is a Postdoctoral Research Associate funded by the OPALS programme. His work focuses on developing and scaling a novel productivity-based metric of rangeland vegetation condition, as well as mapping woody encroachment in a holistically managed ranch using remote sensing and machine learning.

Stephanie Cherington-Rimmell
Head of Development for the Faculty of Environment, Science and Economy. Steff has a background in developing partnerships and managing philanthropic relationships for the University, principally in environmental research. Steff is helping to develop additional projects expanding on the core OPALS programme.
