INTRODUCTION

I am Professor of Mechanical Engineering with a specialty in mechanics of materials and computational mechanics.  Prior to joining Cal State LA, I was Professor in a higher education school of engineer: Centrale Lille. I am still having interaction with my former institution and my research are developped in a synergy between France and USA where I am developping activities in the field of Bio Medical Engineering.

TEACHING ACTIVITIES

RESEARCH

My reserach activities are based on the triptych of mechanics of materials: experimental characterizationm constitutive modelling, and numerical and computational methods.

I am more focused on soft polymers and bio-polymers. My activities can be summarized in 3 fields:

• Behavior, and damage of synthetic polymers
• Behavior of human soft tissue and medical implants,
• Development and design of Medical Devices for patient-specific surgery.

Additional information on my activities can be found on my website

Only the 4 last year are listed. Additional publication can be found on my website.
