Jean-Baptiste Thomas

My research aims to advance a resilient, sustainable, and low-carbon blue bioeconomy. With a background in Industrial Ecology, I use life cycle assessment (LCA) and environmental systems analysis to explore strategies for sustainability, with particular attention to carbon, energy, and nutrient flows.

My doctoral research focused on the emerging Swedish seaweed sector, investigating its potential as a new marine resource and the challenges of integrating seaweed into sustainable value chains. During my postdoctoral work, I expanded this scope to other low-trophic marine biomass, both wild and cultivated, and examined how such resources can help close nutrient loops between land and sea.

As a researcher, my work brings me into direct collaboration with industry actors across the EU, where I support the socio-economic and environmental optimisation of blue value chains, and assess their role in reducing environmental footprints. Much of my focus is on supporting the development of multi-use solutions at sea, blue food and blue materials, and blue carbon projects, and strategies that enhance both ecosystem resilience and societal benefits. Within the blue bioeconomy, I concentrate on low-trophic aquaculture, the use of ambiguous resources such as beach-cast and reed, and marine nature restoration.

I currently work at the division of Water and Environmental Engineering in the department of Sustainable Development, Environmental Science and Engineering (SEED) at KTH, Stockholm. I also have the privilege of working as a theme leader for Sustainable Food Production at KTH Food and leader of the Marine Research cluster at KTH Water.
