Thomas initially studied biology and holds a PhD in ecophysiology and thermal biology, with a specialisation in the study of insects. After working for three years as a postdoctoral researcher in Belgium, he decided to change career paths and joined T&E in 2024 as an analyst on the rail team. Originally from France, Thomas speaks both French and English. Outside of work, he remains passionate about insects, enjoys horse riding when he finds the time, and is into rock music, video games, and pop culture in general.
