Thierry Epicier

Thierry Epicier is an Emeritus Researcher at the Department of Materials Science and Engineering, Claude Bernard Lyon 1 University, affiliated with the CNRS unit IRCELYON (UMR 5256). His research focuses on Environmental Transmission Electron Microscopy (ETEM) to study nanocatalysts under operando conditions, including gas and temperature environments. He leads the MEME group (Methodologies in Environmental Microscopy) and coordinates major projects like the ANR 'WATEM' (2020-2023), analyzing water interactions in aerosols and catalytic systems. Dr. Epicier holds a State Doctorate in Materials Science from INSA Lyon and has extensive experience in electron microscopy techniques, including development of software tools like Diffraction-Workshop and contributions to deep learning approaches for nanoparticle tracking. His academic roles include organizing international microscopy congresses (e.g., EMC2016) and teaching advanced microscopy courses at institutions like Texas A&M University.

Research interests span heterogeneous catalysis, nanoparticle dynamics, and environmental applications of ETEM. Key achievements include pioneering studies on Pd-Au core-shell catalysts, in situ observation of catalytic deactivation mechanisms, and the use of neural networks for automated nanoparticle analysis. He has held leadership positions in CNRS federations (e.g., METSA) and served on ANR evaluation committees. Current work explores cloud formation mechanisms via water condensation studies in ETEM, bridging nanoscale materials science with atmospheric chemistry.

Teaching responsibilities include advanced microscopy training programs and M2 courses on materials characterization. His lab facilities include the IRCATECH characterization platform with operando capabilities. Despite his emeritus status, Dr. Epicier remains active in cutting-edge projects, emphasizing real-time material behavior under functional conditions.
