Présentation

Laurence Le Coq is Professor in Environmental Engineering at IMT Atlantique. She is Dean for Research & Innovation of [IMT Atlantique](https://www.imt-atlantique.fr/fr). From 2017 to 2019 she was Vice Dean for Research & Innovation of IMT Atlantique and Dean for Research & Innovation of Mines Nantes from 2015 to 2017. From 2008 to 2015, she was in charge of the *Energy system & environmental engineering* department at Mines Nantes, as well as deputy director of the Doctoral School in Engineering science. She was deputy director of [GEPEA](https://www.gepea.fr/) laboratory (UMR CNRS 6144) from 2012 to 2020. Her research activitiy is conducted in [GEPEA](https://www.gepea.fr/) laboratory, a joint research unit merging CNRS, Nantes University, ONIRIS and IMT Atlantique. It deals with mass transfer and particle transport through porous media. She is author of more than 60 publications in international peer-review journals and more than 80 communications in international congress. Her scientific skills are related to : \- Aerosol : Transport, capture et resuspension at fluid/solid (porous) interface – application to air depollution and gas separation for energy valorisation or environmental issues. \- Gazeous pollutants : Transfer w/w.o. reaction at fluid/solid (porous) interface – application to COV, PAH and inorganic compounds adsorption for air, fumes and syngas treatment. \- Pourous media : Structural and physico-chemical characterisation in relation with mass transfer / flow through porous media – application to new carboneceous adsorbant and filter clogging. ### **[Page perso](https://www.imt-atlantique.fr/fr/personne/laurence-le-coq)**
