Mathieu Leocmach

Mathieu Leocmach is a CNRS Researcher (Chargé de recherche) at the Institut Lumière Matière in Villeurbanne, France, a position he has held since October 2015. His research focuses on soft matter physics, particularly the mechanics and dynamics of colloidal systems, gels, and active matter. He collaborates extensively with researchers across France and internationally, contributing to fundamental understanding of complex fluid behavior and material properties.

Dr. Leocmach's educational background includes:

• Habilitation à diriger les recherches (HDR) from Université Claude Bernard Lyon 1 (2021)
• PhD in Engineering from University of Tokyo (2008-2011)
• Master in Engineering from University of Tokyo (2006-2008)
• Master from École Polytechnique (2002-2005)

Leocmach's research spans multiple areas of soft matter physics with emphasis on the micromechanics of gels, active matter systems, and glass transitions. His work combines experimental approaches with theoretical insights to understand how microscopic structures determine macroscopic material properties. He has made significant contributions to understanding fracture mechanics in soft materials, the behavior of active colloids, and the fundamental principles governing phase transitions in complex fluids.

His recent publications demonstrate a clear trajectory from fundamental studies of colloidal glasses and gel mechanics toward more applied research on pressure-sensitive adhesives and biomaterials. The work shows increasing focus on practical applications while maintaining strong theoretical foundations, with collaborations spanning physics, materials science, and engineering disciplines.

Scientific recognition includes:

• SOFT-FIRE Award from Société Française de Physique (2014)

Leocmach has secured multiple research grants as principal investigator or key collaborator, including the VITRIPSA project (ANR-21-CE06-0025) on nanostructured adhesives, GelBreak on gel mechanics, and Micromechanics of Gels. His funding portfolio demonstrates strong support from major French research agencies including the Agence Nationale de la Recherche and Centre National de la Recherche Scientifique.

As a CNRS researcher at Institut Lumière Matière, Leocmach is part of a vibrant soft matter research community collaborating with physicists, chemists, and engineers. His work bridges fundamental physics with practical applications in materials science, contributing to both theoretical understanding and potential industrial applications of soft materials.
