Rolf is a scientist, academic and administrator and has a passion for understanding natural phenomena. With a PhD in biochemistry and a bachelor’s degree in business administration, he has dedicated his career to advancing scientific knowledge and making meaningful contributions to his field, through leading and administering teams of academics and students.
Before joining the Ongava Research Centre (ORC), he served as Professor in the Biodiversity Research Centre at the Namibia University of Science and Technology. This role allowed him to engage in research, mentor postgraduate students, and contribute to the academic community by guiding junior personnel. Previously, he held the position of Dean of the Faculty of Natural Resources and Spatial Sciences, where he played a key role in shaping educational programmes and fostering excellence in teaching and research.
His passion for research is reflected in his list of publications. Despite being predominantly an administrator, he has authored over 30 scientific journal papers, exploring various aspects of biochemistry and an appreciation of natural resources. Additionally, he's contributed to ten book chapters and has edited three books, aimed at disseminating knowledge and sharing insights with fellow researchers and students. He has also co-authored a field guide on the succulent Euphorbias of southern Africa.
His current research interests lie in the fascinating realms of dryland and microbial ecology, while continuing with studies of Euphorbia plants. These unique ecosystems and their intricate relationships with microorganisms hold great significance for sustainable resource management and the preservation of biodiversity in arid regions. By delving into these subjects, he hopes to contribute to a deeper understanding of our natural world and its delicate balance.
He has actively participated in many national and international conferences, delivering more than 120 presentations and posters to share his research findings and exchange ideas with fellow scientists. Additionally, he has written 12 popular scientific articles to bridge the gap between scientific research and the public, fostering a greater understanding and appreciation for science.
Through his research, publications, and leadership roles, he aims to make a lasting impact in biochemistry and natural resources. He is driven by a genuine passion for discovery, and believes that by expanding our knowledge and understanding, we at the ORC can contribute to a more sustainable and harmonious coexistence with our environment. He considers it a privilege to be part of this incredible journey, and looks forward to continuing his contributions to the scientific community.

Acoustic monitoring, functional ecology, political ecology
Frowin is an avian ecologist by training, with a penchant for interdisciplinarity. Over the years, his research foci have diversified and now range from functional ecology and land-use to political ecology and quantitative geography. Frowin has participated in ecological research across southern Africa. His years-long involvement with the National Geographic Okavango Wilderness Project culminated in a doctoral degree, which he completed in 2023 through the Victoria University of Wellington/Te Herenga Waka in New Zealand. Since pursuing a research career, Frowin’s trajectory largely steered him away from Namibia, but his role at the Ongava Research Centre signals an opportunity to apply himself and his expertise in the country of his birth.
PhD | Wildlife Ecologist

Carnivore ecology, landscapes of fear, species interactions, camera trapping
Stéphanie mainly studies behavioural and spatial ecology, with a specific emphasis on carnivores and prey-predator relationships. She focusses on the ‘landscape of fear’ between prey and predator but also between predators themselves. She is particularly interested in the complexity of species interactions, both negative and positive, and understanding their coexistence. Her research relies heavily on direct behavioural observations in the field, GPS tracking devices and camera trapping.
With a group of international and local collaborators, Stéphanie coordinates the Greater Etosha Carnivore Programme. The programme's aim is to understand the drivers of carnivore distributions and abundances in the Greater Etosha Landscape.
At Ongava Research Centre, she also curates our long-term camera trap image database and collaborates with several teams on the development and improvement of artificial intelligence for automated wildlife image classification.

Simeon grew up in a village called Oshivanda in Namibia’s Omusati Region. After finishing high school in 2007, he decided to move to Outjo in the Kunene Region the following year, in search of employment. There he eventually took up a role at Ongava Game Reserve (OGR). While Simeon was initially contracted to assist with de-bushing efforts on the Reserve, he was permanently recruited as part of OGR’s anti-poaching units in 2010. During this time, his duties primarily involved fence patrol, as well as rhino tracking. In 2013, Simeon accepted a position as a field technician at Ongava Research Centre (ORC’s), where he’s been especially involved in camera-trap-based research. These involvements have led to several research outputs, including co-authored peer-reviewed publications.
