Isabelle AUJARD

Paris

 

Biography

I studied at the university Pierre et Marie Curie (Paris VI) and I specialized in organic chemistry. After a PhD in synthesis methodology (Pr. A. Alexakis, Paris VI) and a post-doctorate on the synthesis of the Tridemethylisovelleral, a potent cytotoxic agent (Pr. O. Sterner, Lund University, Sweden), I joined the Chemistry Department of the Ecole Normale Supérieure (Paris). I was here recruited as a research engineer and I continued research at the interface of chemistry, biology and physics in L. Jullien's group. I then started to work on the synthesis of photolabile protecting groups, caged compounds and fluorogenic ligands compatible with biological applications.

Research topics

I work mostly on the synthesis, characterization and physicochemical study of chemical species with tailored spectroscopic properties.

Fields of interest

Photolabile protecting groups, caged compounds, fluorescent ligands.
