Prof. Yohan Payan,
TIMC-IMAG, Univ. Grenoble Alpes / CNRS, Grenoble France
Biomechanics for computer-assisted medical interventions
CNRS Research Director, Yohan Payan has developed a research team dedicated to
biomechanics for Computer Assisted Surgery and received the 2012 Senior Price of the
French Biomechanics Society. During the last fifteen years, he has co-supervised 30 PhD
students, written 300 papers and edited two books. During the same period, his
international experience was strong since he spent two sabbatical years in Chile (Univ. of
Santiago) and Canada (UBC, Vancouver) and was invited as a keynote speaker in twenty
international conferences. Yohan Payan has also developed an important link with industrial
applications, being the inventor of 15 international patents. He was the coordinator of the
ANR TecSan “Inteligent Diabetic Sock” project (2010-2014) that led to the creation of the
Texisense Company, laureate of the French National Price for Innovative Industries in the
domain of pressure ulcer prevention.
Currently, Yohan Payan is the head of the Grenoble CAMI team (Computer Assisted Medical
Interventions – 50 people) and the deputy director of TIMC-IMAG Laboratory (wwwtimc.
imag.fr – 250 people). He also coordinates the Eccami platform (www.eccami.org).
Abstract of the presentation:
The clinical objective of CAMI is to develop systems that assist the physician in the practice
of minimally invasive diagnostic or therapeutic actions. The main scientific objectives that
result from this clinical goal include the design and development of (1) reconstruction
methods, image processing and data fusion, (2) models describing organs and clinical
procedures, (3) simulators enabling action planning, monitoring and prediction of outcomes;
and finally (4) guiding systems to realize an action as planned. Industrial dissemination of the
research results is also an objective of the CAMI team.
Yohan Payan’s research interests concern the biomechanical modeling of soft tissues as well
as some cognitive aspects when devices have to be designed and accepted by patients
(mainly in the context of rehabilitation). The public lecture will introduce the field of
Computer-Assisted Medical Interventions (CAMI) while focusing on the areas of Yohan
Payan’s research expertise, namely the biomechanical modeling of soft tissues. He will
describe the main challenges researchers face in the future, i.e. the automatic generation of
patient-specific models of organs and the integration of simulation tools into medical
devices enabling real-time computations of these models. These challenges will be
illustrated in the domains of plastic and maxillofacial surgery and procedures for the
prevention of pressure ulcers (in paraplegic patients and diabetic persons).
