The originality of the research carried out by Guillaume Haïat lies in the intrinsic coupling between fundamental research issues (e.g. study of multiple diffusion in trabecular bone) and applied research (development of medical devices for the decision support for surgeons).
After an experience as research engineer at Saint-Gobain Research, Guillaume Haïat carried out his doctoral thesis work from 2000 to 2004 within the Commissariat à l'Energie Atomique (CEA, Saclay, France), on the development of an ultrasonic approach to characterize the reactor pressure vessels of nuclear power plants. This method is currently used in the nuclear industry by Orano (formerly Areva).

He is co-founder of the company WaveImplant SAS, created in 2019, which is developing a groundbreaking technology consisting in using ultrasound for the first time to measure the stability of dental implants. WaveImplant was part of the first promotion of the CNRS RISE program, which was a great help for its development. WaveImplant is a winner of the French Tech Tour in 2021 and has received the “Gold” label from EIT Health. The licenses of two patent applications have been transferred within WaveImplant.

Guillaume Haïat is also co-founder of the company ImpacTell SAS which was created in November 2022 in order to develop a medical decision support device for orthopedic surgeons in the context of total hip prostheses. ImpacTell is incubated by Descartes Innovation, which depends on the Paris-Est University and has obtained the Deeptech label. The licenses of 4 patent applications managed by CNRS Innovation are being transferred to ImpacTell, a letter of intent having been signed.

Guillaume Haïat has experience in the management of international research projects (he is director of the Franco-Canadian UltraSound Research Laboratory, IRP CNRS). He is responsible for 4 projects funded by the National Research Agency (ANR). He is the leader of the ERC BoneImplant project (Consolidator Grant 2015) entitled “Monitoring bone healing around endosseous implants: from multiscale modeling to the patient’s bed”. This project was followed by two ERC Proof of Concept projects (2019 and 2021) whose objective is precisely to promote the work carried out within the framework of the ERC BoneImplant. He is also the leader of the Prématuration Ostéome project funded by the CNRS in 2019 and has obtained 3 “Generation PI” projects funded by SATT Erganéo. Finally, he initiated many industrial collaborations mainly in the field of biomechanics. He is an associate professor at the Ecole de Technologie Supérieure (ETS) in Montreal QC (Canada).
