Research Interests

My lab is conducting a highly interdisciplinary research at the interface of biology, chemistry and material sciences with applications for Synthetic Biology, Nanotechnology and Biotechnology.

Cells are the most sophisticated machinery producing selectively and simultaneously hundreds of thousands of complex molecules. Our group is developing and applying new synthetic molecular biology pathways for the bioproduction of “living molecules” in bacteria. These molecules may exhibit intriguing functions with diverse in vivo applications, from medicine to energy or offering a production route of new classes of materials holding interesting physical capabilities (optics, electronics or catalysts).

In this context, my lab is currently focusing on developing synthetic biological tools for the expression of oligonucleotides and their self-assemblies into DNA nanostructures in bacteria. Defined DNA nanostructures inside living cells are investigated to confine and enhance specific chemical reactions for metabolic engineering or to study the effects of spatial localization on multi-component biomolecular pathways.
