Memory Professors and Supervisors in France

Julio Parra-Martinez is a Permanent Professor at the Institut des Hautes Études Scientifiques (IHES) since 2024. Originally from Spain, he completed his undergraduate studies at the University of Valencia, followed by a MASt in Applied Mathematics from the University of Cambridge in 2015, and a PhD in Physics from UCLA in 2020. Prior to joining IHES, he was a Sherman Fairchild Prize Postdoctoral Fellow at Caltech for three years and an Assistant Professor at the University of British Columbia for one year. His educational background includes: Undergraduate: University of Valencia, Spain MASt in Applied Mathematics: University of Cambridge (2015) PhD in Physics: University of California Los Angeles (2020) Parra-Martinez is a theoretical physicist specializing in quantum field theory, scattering amplitudes, gravitation, effective field theories, and string theory. His recent work focuses on importing techniques from particle physics to classical general relativity, with applications to gravitational-wave and black-hole physics. He has made significant contributions to understanding how scattering amplitude techniques, originally developed for particle colliders, can be applied to gravitational systems. His research bridges the gap between quantum field theory and classical gravity, particularly in the context of binary black hole systems and gravitational wave emission. His publication record shows a consistent focus on using scattering amplitude methods to tackle problems in gravitational physics. Over the past five years, he has published extensively on post-Minkowskian expansions, gravitational waveforms, soft theorems, and connections between quantum field theory and classical gravity. His work often involves collaborations with leading researchers in the field and demonstrates how techniques from particle physics can be adapted to gravitational systems, particularly in the context of extreme mass ratio binaries and gravitational wave physics. Among his notable scientific achievements are: Mayhew Prize (2015) Fulbright Fellowship (2015-2020) Sherman Fairchild Prize Postdoctoral Fellowship Parra-Martinez is actively involved in the theoretical physics community, with numerous upcoming seminars, talks, and lectures scheduled through 2026 at institutions worldwide including ICTP Trieste, Universidade de Sao Paulo, University of Southampton, and others. His research program continues to explore the connections between particle physics techniques and gravitational physics, with particular emphasis on gravitational wave astronomy and black hole physics.

University of RennesFrance

Eric Collet is a University Professor and Head of Department at the Institute of Physics of Rennes (IPR), a joint research unit of CNRS and Université de Rennes. His work centers on ultrafast photoinduced phase transitions, spin-crossover materials, and the control of functional materials using light and THz excitation. He leads a dynamic research team and is deeply involved in international collaborations, particularly through the IM-LED International Laboratory with Japan. University: University of Rennes School: Institute of Physics of Rennes Department: Department of Materials and Light Academic Rank: Professor Email: eric.collet@univ-rennes.fr Professor Collet's research explores the ultrafast dynamics of molecular and condensed matter systems, especially those exhibiting multistability and photoresponsiveness. His work combines femtosecond optical and X-ray techniques to probe structural and electronic changes at atomic scales. Key areas include spin-crossover phenomena, photomagnetism, ferroelasticity, and nonlinear phononics. He investigates how light can trigger cooperative responses in materials, leading to persistent phase transitions with applications in photonics and memory devices. The recent publications of Eric Collet reveal a strong focus on ultrafast structural dynamics, photoinduced charge and spin transitions, and the coupling of electronic states with lattice distortions. His team frequently employs advanced X-ray methods at large-scale facilities like ESRF and LCLS. The research spans from fundamental quantum dynamics to applied materials science, with recurring themes in symmetry breaking, cooperative switching, and room-temperature photoresponse in molecular systems. Scientific awards and recognitions include: CNRS Silver Medal (2020) Louis Ancel Prize, French Physical Society Hot Paper selection in PCCP (2019) Very Important Paper recognition in Eur. J. Inorg. Chem. (2019) News & Views feature in Nature Chemistry (2020) Eric Collet actively mentors PhD students and postdoctoral researchers, and has supervised numerous publications in top journals. He has led major scientific initiatives such as the UCM2018 symposium and JMC2021 conference. His research is supported by grants from ANR, CNRS, and the Institut Universitaire de France. He collaborates extensively with institutions in France, Japan, and beyond. His research is conducted primarily within the Department of Materials and Light at the Institute of Physics of Rennes. He co-directs the IM-LED International Laboratory with Prof. Shin-ichi Ohkoshi (University of Tokyo) and collaborates with groups in Bordeaux, Lebanon, and Japan. His lab specializes in time-resolved X-ray diffraction, ultrafast spectroscopy, and nonlinear optical control of materials.
