Research interests

Dr Hauke Kegler is Programme Area Manager for Programme Area 5 “Societal Impact”. His work sits where marine research meets policy and practice. He focuses on making biodiversity data accessible and usable for decision-making, and on involving local stakeholders in managing coastal ecosystems.

His background is in marine microbial ecology. In his doctoral research at ZMT he studied bacterial communities in the coral reefs of the Spermonde Archipelago, Indonesia. He looked at how water quality, human impact and habitat type shape these communities, and what that means for biogeochemical cycles and coral larval settlement.

From 2018 he coordinated the Tanzanian-German project NeDiT (“New Digital Technologies for Marine Biodiversity Data Handling in East Africa – Data Linking People”) together with the Institute of Marine Sciences in Dar es Salaam. During the same period he worked in WIOGEN (West Indian Ocean Governance & Exchange Network). WIOGEN brought together researchers, policymakers and educators to support regional ocean governance in the Western Indian Ocean. In these projects he co-authored policy recommendations on sharing marine biodiversity data, presented them at the Nairobi Convention’s Science-to-Policy Dialogue, and co-edited the Western Indian Ocean Information Management Strategy (2024).

His later projects were PaMo (Participatory Modelling for Nature-based Solutions) and MarLi-EBES. PaMo combined local knowledge and scientific modelling to support nature-based solutions in Madagascar and Tanzania. MarLi-EBES studied how marine litter affects biodiversity and ecosystem services in Ecuador’s mangroves.
