Jean-Baptiste is a joint PhD candidate between Stockholm Resilience Centre, Stockholm University, and the Global Economic Dynamics and Biosphere programme (GEDB) at the Royal Swedish Academy of Sciences.
As a PhD-candidate in Sustainability Science, his primary interest lies in exploring the intertwined relationship between humans and marine ecosystems in the Anthropocene, with the ambition to provide empirical novel approaches and analytical methods for understanding social-ecological system dynamics around the world.
His research encompasses multiple scales and systems, ranging from the Hawaiian archipelago and indicators for effective coral management, to the seafood industry at a global scale and the role of transnational corporations and the financial sector.
Jean-Baptiste has a background in natural science with an undergraduate degree in Biology of Organisms, Populations and Ecosystems from University Paul-Sabatier (France), and a MSc in Ecology from Stockholm University. After defending his MSc thesis in 2013, he joined the Global Economic Dynamics and the Biosphere program at the Royal Swedish Academy of Sciences as a research analyst for one year, before starting a PhD in Sustainability Sciences.
At Stockholm Resilience Centre, Jean-Baptiste is affiliated to the theme Governance of coastal and marine systems and the stream Patterns of the Anthropocene, working primarily with Magnus Nyström, Albert Norström, Henrik Österblom and Beatrice Crona. Other collaborators include researchers from the Center for Ocean Solutions - Stanford University, Hawaii University, NOAA, Bangor University, Lancaster University, Leibniz Center for Tropical Marine Ecology and University of St Andrews.
The Hawaiian case study is run in collaboration with the NCEAS group Ocean Tipping Points that seeks to identify critical thresholds and indicators for effective coral reef management in the Hawaiian Islands.
Jean-Baptiste is also a member of the Resilience Alliance Young Scholars (RAYS) network.

While environmental filters are well-known factors influencing community assembly, the extent to which these modify species functions, and entire ecosystem processes, is poorly understood. Focusing on a high-diversity system, we ask whether environmental filtering has ecosystem-wide effects beyond community assembly. We characterise a coral reef herbivorous fish community for swimming performance based on ten functional trai...

Anthropogenic changes to the Earth now rival those caused by the forces of nature and have shepherded us into a new planetary epoch – the Anthropocene. Such changes include profound and often unexpected alterations to coral reef ecosystems and the services they provide to human societies. Ensuring that reefs and their services endure during the Anthropocene will require that key drivers of coral reef change – fishing, water qu...

Fishery reform in North America and Europe has substantially improved the prospects for recovery of ecosystems affected by overfishing. Costello et al. (1) draw from lessons learnt and suggest, in their view, commonsense approaches for improved resource management, including fishing to maximize long-term catch and rights-based fishery management approaches that optimize economic values. They identify global prospects by 2050 a...

Keystone species have a disproportionate influence on the structure and function of ecosystems. Here we analyze whether a keystone-like pattern can be observed in the relationship between transnational corporations and marine ecosystems globally. We show how thirteen corporations control 11-16% of the global marine catch (9-13 million tons) and 19-40% of the largest and most valuable stocks, including species that play importa...
