Dr. Sébastien Deguy is a French physicist and materials scientist noted for contributions to nanostructured materials, polymer thin films, and surface characterization. His work bridges experimental techniques and theoretical interpretation, engaging with interdisciplinary laboratories and international collaborations. Deguy's career includes leadership roles in research institutes, extensive publication in peer-reviewed journals, and mentorship of students who now occupy academic and industrial positions.
Deguy was born in France and pursued higher education within the French higher education system at institutions including the École Normale Supérieure and Université Paris-Saclay. His doctoral research drew on methodologies from Condensed Matter Physics and instrumentation developed at national facilities such as the Synchrotron SOLEIL and the European Synchrotron Radiation Facility. During graduate study he collaborated with researchers affiliated with the Centre National de la Recherche Scientifique and training programs associated with the Commissariat à l'énergie atomique et aux énergies alternatives. His early mentors included senior figures connected to laboratories that interface with the French Ministry of Higher Education, Research and Innovation and European research infrastructures.
Deguy's academic trajectory includes appointments at major French research centers and universities, with joint positions linking departments of Physics and materials laboratories affiliated to the CNRS and CEA. He led projects in collaboration with teams from the Institut Laue-Langevin, the Max Planck Society, and the Lawrence Berkeley National Laboratory, focusing on characterization protocols for thin films and interfaces. His experimental programs often integrated techniques such as grazing-incidence X-ray scattering developed at facilities like ESRF and SOLEIL, and microscopy platforms used by groups at the Laboratory for Photonics and Nanostructures and the Minatec community. Deguy has been principal investigator on grants from the European Research Council and national funding bodies including the Agence Nationale de la Recherche.
Deguy's publication record features studies on self-assembled polymers, block-copolymer lithography, and nanoscale ordering in thin films published in journals that include collaborations with researchers associated with Nature Materials, Advanced Materials, and Physical Review Letters author groups. He contributed to methodological advances in in situ characterization that intersect with techniques championed by teams at Brookhaven National Laboratory, Argonne National Laboratory, and Sandia National Laboratories. Deguy co-authored works addressing the interplay of shear fields and nanostructure ordering, following theoretical frameworks related to concepts developed by scholars from Princeton University, Massachusetts Institute of Technology, and University of Cambridge. His papers often cite and build upon foundational studies from investigators at Columbia University, Harvard University, and ETH Zurich. Deguy's research has informed applied developments in nanolithography exploited by groups at IMEC, CEA-Leti, and industrial partners such as STMicroelectronics and Intel Corporation.
Deguy has been recognized with honors from national and international organizations, including distinctions linked to the CNRS and awards supported by the Société Française de Physique. He received competitive research support from the European Research Council and prizes associated with collaborative networks that include the European Commission's framework programs. Deguy's contributions have been cited in award presentations by institutions like the Institut Universitaire de France and national academies such as the Académie des sciences.
In his teaching roles Deguy delivered courses and supervised research students in programs affiliated with Université Paris-Saclay, École Polytechnique, and graduate schools connected to the French National Centre for Scientific Research. He supervised doctoral candidates who later joined research groups at institutions including the University of California, Berkeley, University of Oxford, and industrial research centers at Nokia Bell Labs and Philips Research. Deguy contributed to curriculum development in advanced materials and nanoscience offered through partnerships with the European School of Materials and consortiums tied to the Horizon 2020 initiative.
Deguy has served on scientific committees for facilities such as the SOLEIL and the ESRF, and on program advisory boards for conferences organized by societies including the Materials Research Society and the European Materials Research Society. He has acted as a reviewer and panel member for agencies such as the Agence Nationale de la Recherche, the European Research Council, and international funding bodies connected with the National Science Foundation and national ministries. Deguy also participated in editorial activities for journals aligned with publishers like Springer Nature and Elsevier, and organized thematic symposia in collaboration with laboratories tied to the Institut Charles Sadron and the Laboratoire de Physique des Solides.
