Dr. Lenihan is an ecologist who studies the impact of human activities on marine ecosystems, fisheries management, population and habitat restoration and ecotoxicology. His work combines theoretical ecology and fisheries science: he uses a combination of modeling and field experiments to contribute to policies on fisheries management, biological diversity and adaptive management. He makes his scientific expertise available to fishing communities and fisheries departments to develop collaborative conservation and fisheries management programs. For the past 22 years, he has been associated with the Longitudinal Coral Reef Ecology Research (LTER) program in Moorea.
Since 2019, as co-director of the Rāhui Center, he contributes to the strategic direction of the project in close collaboration with Dr. Tamatoa Bambridge. He manages the ecology component of the project and especifically works with local communities to develop adaptive management strategies (including fish size management options) and trains fishers in collaborative protocols and tools.
