Lotanna Micah Nneji, PhD (He/His)

Assistant Professor

I am an interdisciplinary scientist interested in understanding the diversity, ecology, population genetics and distribution patterns of animals such as invertebrates, fishes, amphibians, reptiles, birds and mammals. My research incorporates natural (ecology, genetics and evolution), physical (climate) and social sciences to understand wildlife ecology and improve conservation. I am also interested in communicating science to the public through outreach programmes and storytelling.

Segun Olayinka Oladipo, PhD

Postdoctoral Research Fellow

Dr. Segun Olayinka Oladipo, PhD
Adjunct Lecturer/ Postdoctoral Research Fellow
I am an ecologist and conservation biologist with deep expertise in the ecology, genetics, and conservation of fish and other vertebrates. My research integrates taxonomy, biodiversity science, and ecological investigations to understand how organisms respond to environmental change and to inform sustainable management strategies.
I am a National Geographic Society Explorer, a member of the American Fisheries Society, the American Elasmobranch Society, the Society for Conservation Biology, as well as the West and Central Africa Elasmobranch Coalition and the West African Marine Fish DNA Barcoding Network (WAMBA-Net), a collaborative effort to create a regional DNA reference library and management for marine fish biodiversity in the region.
I have led several externally funded projects supported by the National Geographic Society, Save Our Sea Foundation, Rufford Foundation, PADI Foundation, Society for Conservation Biology, and many more, focusing on mitigating climate change risks as well as conservation of threatened stingrays, sharks, and broader aquatic ecosystems. The work bridges field surveys, molecular laboratory analysis, bioinformatics, and community-based conservation, advancing evidence-based strategies for biodiversity protection and sustainable ecosystem management across Africa and the world.
