Thomas Grevesse is a scientist driven by a deep curiosity for how complex biological systems operate—and how they shape human health and the environment.His research journey began with a PhD at the University of Mons (Belgium), where he explored the biomechanics of neurons. Starting with single cells to probe their vulnerability to traumatic brain injury, he moved on to study how neuronal networks form under mechanical cues.

These interdisciplinary projects, at the crossroads of bioengineering, physics, and cell biology, laid the foundation for his systems-level approach to science.
 

At Harvard University, during his postdoctoral fellowship, Thomas applied this knowledge to the emerging field of organs-on-chips. There, he developed microengineered platforms to mimic the structure and function of human organs—such as the brain and blood vessels—allowing him to 
study disease mechanisms and test drugs in dynamic, physiologically relevant systems.

Motivated by growing concerns about the environment, Thomas shifted his focus to microbial ecology. He completed a second PhD at Concordia University (Canada), investigating how microbial communities function and shape global biogeochemical cycles. His work centered on 
Arctic Ocean microbiomes, where he studied how these communities adapt to extreme cold, respond to climate change, and impact broader ecosystems.

From polar cold to scorching heat, Thomas now leads pioneering research on marine microbiomes in the Arabian Gulf—the hottest sea on Earth. His goal: to understand how microbial life persists under extreme heat, and what that reveals about the future of ocean life in a rapidly warming world.
