Présentation

Ingénieur de formation, Yohan Payan est Directeur de Recherche CNRS (Section 07) au sein du Laboratoire TIMC (recherche Translationnelle et Innovation en Médecine et Complexité) à l'Université Grenoble Alpes. Ses principaux intérêts de recherche concernent la modélisation biomécanique par éléments finis des tissus mous humains et leur intégration dans des dispositifs d’assistance médico-chirurgicale. Ces modèles ont des applications pour la chirurgie plastique et maxillo-faciale, le traitement des cancers du sein et du poumon, la neurochirurgie, l'orthopédie, ou la prévention des plaies de pressions. Pour chaque organe (visage, langue, sein, poumon, cerveau) ou structure musculo-squelettique (incluant les os et les tissus mous tels que les muscles, les tendons, la graisse et la peau), un modèle patient-spécifique (« jumeau numérique ») est élaboré et utilisé en simulation pour assister le geste clinique.
