Jean-Marc Delhaye earned his doctorate in physics from Grenoble University after graduating from the Grenoble National Polytechnic Institute. Thereafter, he joined CEA/Grenoble and held several key positions, including Head of the Fundamental Research Laboratory and Head of the Industrial Thermal-Hydraulics Laboratories. He ultimately obtained the title of Director of Research for Thermal-Hydraulics studies.

In addition to his research leadership, Delhaye was a professor at École Centrale Paris—a French top-tiered engineering school—and at the French National Institute for Nuclear Science and Technology. For over 20 years, he has been a faculty member in the Department of Mechanical Engineering at Clemson University.

Beyond academia, Delhaye co-founded and served as Co-Editor-in-Chief of Multiphase Science and Technology and is a past president of the Assembly for the International Heat Transfer Conferences. He has also contributed to several international editorial advisory boards, including the International Journal of Multiphase Flow, Experiments in Fluids, the International Journal of Heat and Mass Transfer, and International Communications in Heat and Mass Transfer.

A widely recognized expert, Delhaye has lectured in 36 countries and served as an international consultant in Venezuela, the Netherlands, Argentina, the United States, and for the European Commission.

His scholarly contributions include authorship, co-authorship, or editorial work on 13 books, along with more than 80 peer-reviewed articles.

Numerous honors recognized Delhaye’s achievements. A laureate of the French Academy of Sciences, he received, in particular, the Grand Prize of the French Society for Hydraulic Engineering, the Technical Achievement Award from the Thermal Hydraulics Division of the American Nuclear Society, and the Clemson University Board of Trustees Award for Faculty Excellence.

He is a Fellow of the American Nuclear Society (ANS), a Fellow of the American Society of Mechanical Engineers (ASME), and a Nureth Fellow from ANS. A Chevalier of the French Order of Academic Palms, he was awarded the City of Grenoble Vermeil Medal.
