Overarching research goal

We aim to understand the functioning of present and future reef systems. We investigate what promotes or supports reef integrity, biodiversity, and the benefits reefs provide to people. We ask why and how are reefs changing and how are these changes reconfiguring reef-human connections. We study what underpins the natural survival of reef building corals in a changing world whilst embracing the emergence and persistence of non-coral dominated reefs. With this knowledge we seek to orient both conventional and proactive strategies of reef conservation and restoration.

We investigate corals’ responses to a range of pervasive ocean pollutants including microplastics, herbicides, and sunscreen filters. We ask whether a) corals react differently to microplastics of different shapes, b) microplastics disrupt key ecological functions of corals, and c) polyps undergo high levels of stress when inspecting or ingesting microplastics. Work in this theme is carried out at the Green Island Marine Research Station, at our Marine Experimental Facility (MAREE), and is developing in further novel directions in collaboration with the Microsensor Group in the Max Planck Institute for Marine Microbiology. In the field, we have also aimed at understanding how coral reefs living in atypically turbid and polluted conditions function. In this context, we joined the research efforts of Pontificia Universidad Javeriana de Cali and Fundacion Ecomares in Varadero reef which may paradoxically be one of the best coral reefs n the continental shelf of Colombia despite being exposed to heavy industrial and sewage waste.
