Dr. hab. , CEA Fellow​

Dr-Hab Jean-Paul Garandet has been a research director at CEA since 2001, where he leads a research group at the interface between CEA-Liten and CEA-List teams, focusing on the modeling and experimental validation of additive manufacturing processes.

He graduated from Telecom Paris in 1983 with a major in electronics and physics. He holds a doctorate in materials science from the Institut National Polytechnique de Grenoble (1989), where he also obtained his habilitation (specialization: mechanics) in 1998.

He is co-author of over 70 patents and 100 articles in peer-reviewed journals.​

Research Activities​​

Jean-Paul Garandet has been working on heat and mass transport phenomena at the interface between the materials and mechanics communities for over 30 years.

A major part of his research activity has focused on crystal-growth solidification of semiconductor materials, with particular emphasis on silicon for photovoltaic applications, and he is now turning his attention to additive manufacturing problems on metallic alloys.

These activities have also led him to tackle issues revolving around diffusion, capillarity and high-temperature physicochemistry.

A specific feature of Jean-Paul Garandet's work is his will to build bridges between experimentalists and numerical modelling experts, with an approach based on the identification of first-order parameters in a given problem and the establishment of scaling laws to link them.​​​
