BIO: Jocelyn Bonjour has been a Professor of Heat Transfer and Thermodynamics at the Department of Energy and Environmental Engineering at INSA Lyon, France, since 2005. He received his PhD at INSA Lyon in 1996. He was formerly Professor at the French Institute of Refrigeration (IFFI), Paris, France. His research subjects are linked to liquid-vapor phase change heat transfer. This covers the fundamentals of boiling (e.g. bubble dynamics during boiling) and the application of phase-change to heat exchangers in refrigeration systems or heat pipes for electronic thermal management. He is also involved in energy efficiency of refrigeration or air-conditioning systems (cold rooms, refrigerated trucks…). He has published ca. 100 articles in peer-reviewed journals and as many communications in conference proceedings. He is a regional editor of Elsevier's International Journal of Refrigeration (IJR) and the Chairman of the Committee on the Joint International Heat Pipe Conferences and Symposia (IHPC&S). Beyond his research activities, he was the Director of the Center for Energy and Thermal Sciences of Lyon (CETHIL), a joint research institute of INSA Lyon, CNRS (National Center for Scientific Research) and University Lyon 1 from 2013 to 2018 and has been the director of the Doctoral School of Université de Lyon devoted to Mechanical Engineering, Energy Engineering, Civil Engineering and Acoustics since 2018.
