Théotime was trained as a beekeeper when he was in high school and has kept bees ever since. He studied biology in France before coming to Australia to complete his PhD at Macquarie University. After completing his PhD in 2019, he was hired as a post-doctoral researcher at the University of Sydney.

Théotime has a broad interest in entomology and agriculture. His work focuses on understanding the long-term population dynamics of honeybee colonies under stress. He is an expert in hive monitoring methods, which he uses to understand the effect of pests, insecticides, heat, and other stressors on honeybee colonies.
