Introduction
Hello, I am a French-German Post-doc working the Netherlands in the group of Prof. Sijbren Otto. I'm interested in almost everything which touches chirality: chiral self-sorting and catalytic activity of supramolecular assemblies, chiral symmetry breaking in the context of the origin of biological homochirality (current work); non-linear effects in asymmetric catalysis and sum-frequency generation on chiral metallopolymers (previous work).

Project
Positive non-linear effects (NLE) are phenomena were non-enantiopure catalysts may yield product ee's as high as the enantiopure catalyst. Recently, we have discovered the first example of "hyperpositive" NLEs were the non-enantiopure catalyst yields product ee's even *higher* than the enantiopure catalyst, using ephedrine-based ligands in the asymmetric addition of dialkylzincs to benzaldehyde.
Project
Synthesis and application of chiral metallopolymers as materials for sum-frequency generation.
Project
Design and application of metallopolymers, consisting of a ditopic ligand and a metal salt, in enantioselective catalysis. The polymeric structure allows the catalyst's recovery by precipitation through add. of a counter-solvent, and its reuse in several catalytic runs.
