Short bio
Antoine Tissot is a CNRS research scientist at the Porous Materials Institute of Paris (UMR 8004, CNRS-ENS-ESPCI). Following his PhD in coordination chemistry dedicated to the study of molecular spin crossover nanocrystals at University Paris-Sud under the supervision of Dr. Marie-Laure Boillot, he stayed at University of Geneva with Prof. Andreas Hauser as a postdoctoral researcher (2011-2014, Marie Curie Fellowship) where he studied photophysics of coordination compounds. He was then recruited as CNRS researcher in the Institut Lavoisier de Versailles in 2014 in the team of Dr. Christian Serre and moved to the newly created Porous Materials Institute of Paris in September 2016. He is currently working on the synthesis and functionalization of Metal Organic Frameworks for applications in sensing, catalysis and conductivity.
