Yuna Han

Yuna Han is a Research Fellow at Ircelyon (Institut de Recherches sur la Catalyse et l'Environnement de Lyon), affiliated with Claude Bernard University Lyon 1. Her work bridges engineering, materials science, and environmental chemistry through advanced catalytic research for sustainable development and energy transition initiatives.

Her research portfolio emphasizes atmospheric chemistry and heterogeneous catalysis, with core focus areas including CO₂/CH₄ conversion, biomass valorization, and air/water pollution control systems. She pioneers integrated approaches combining in situ/operando characterization techniques (ESEM/ETEM, microcalorimetry, spectroscopy) with deep learning-enhanced microscopy to analyze nanoparticle reactivity and catalytic processes from molecular models to industrial applications. This methodology supports sustainable chemistry innovations in pollutant recovery and energy transition technologies.

Dr. Han actively contributes to Ircelyon's IRCATECH characterization platform and participates in major scientific initiatives including the VALOTHERBIO thematic school on biomass thermochemical valorization (October 2025) and the institute's annual scientific day. Her recent work on nocturnal atmospheric oxidation mechanisms advances understanding of cloud formation processes and climate impacts through laboratory-replicated atmospheric chemistry.
