Introduction
The research work of Reiko Oda focuses in the field of multiscale design, synthesis and application of nanometric molecular self-assemblies, and their contribution to the understanding of mechanisms and the control of morphology and dynamics at different levels (molecular, mesoscopic up to macroscopic scale). I have investigated the effect of counterions on the assembly properties which lead to original assembly morphologies, particularly made a breakthrough for the development of chiral nanoobjects, quite unique in the community. In parallel, I also developed the synthesis of hybrid chiral organic-inorganic nanostructures with well controlled morphologies based on sol-gel chemistry using these organic assemblies as templates. These nanostructures are developed further in the projects some of which are described below in order to develop nanomaterials with optical, mechanical and biological application in view. She has been independently leading her own group since 1998 and directed 18 PhD. Ongoing projects are funded by various agencies such as Europe (FET-OPEN), ANR, ANR-Internationals, CNRS, JSPS, IdEx, CSC, Regional counsel, University of Bordeaux, etc….She is author of 109 peer-reviewed publications, (H38), 6 book chapters, recently chaired the international Symposium on Chirality (July 2019, 340 participants.). Director of a newly created Fédération de la recherche Chirality in Nouvelle Aquitaine (Ki-NOA).
