Sylvestre Bonnet studies the coordination chemistry of metal complexes in biological and biomimetic environment. By combining inorganic synthesis and photochemistry he makes new light-activatable metal-based anticancer prodrugs for use as targeted anticancer agents with minimal side effects.

Sylvestre Bonnet obtained his PhD in 2005 at the University of Strasbourg, and moved to The Netherlands as a postdoctoral fellow, first in the group of Gerard van Koten (Utrecht), then with Jan Reedijk (Leiden). After obtaining a Veni grant in 2008 in the Chemical Biology group of Bert Klein Gebbink and Antoinette Killian (Utrecht) he moved to Leiden in 2009 where he started a Tenure Track position in Inorganic Chemistry. He obtained a Vidi grant in 2012 and an ERC Starting Grant in 2013, and became Associate Professor in 2015. His expertise lies at the crossing point between inorganic chemistry, photochemistry, and liposomes. His current research interests are light-activated anticancer metallodrugs, photocatalysis, and liposome technologies.
