DESCRIPTION:Prof. Dominique Pioletti\, Institute of Bioengineering and Ins
 titute of Mechanical Engineering\, EPFL\, Lausanne (CH)\nWEEKLY EPFL BIOE 
 TALKS SERIES\n\n(note that this talk is number two of a double-feature sem
 inar - see details of the first talk here)\n\nAbstract:\nTo quote Prof. Cl
 ifford Truesdell\, “dissipation is the rule rather than the exception”
 . The study of this phenomenon is therefore of prime importance if we want
  to obtain a precise description of the mechanical behavior and the biolog
 ical functions of soft tissues. As example\, we previously showed that the
  dissipation arising in knee cartilage during physical activities was resp
 onsible for a local temperature increase in this tissue favoring chondroge
 nesis. Dissipation is however a general term that does not discriminate be
 tween the different dissipation sources at play in soft tissues submitted 
 to dynamic loading. The dissipation sources can be of reversible or irreve
 rsible nature which have fundamental different physical properties. In thi
 s talk\, I will present the way we consider and control the dissipative ph
 enomena in the development of materials such as hydrogels to increase thei
 r mechanical properties. In particular\, I will highlight the central aspe
 ct of dissipation in developing highly adhesive hydrogels or soft material
 s that could be used in the prevention of concussion in sport contact.\n\n
 Bio:\nDominique Pioletti obtained a Master’s degree in Physics at EPFL i
 n 1992. He pursued his education in the same Institution and obtained his 
 PhD in biomechanics in 1997. He developed original constitutive laws for s
 oft tissues taking into account viscoelasticity in large deformation situa
 tions. Then he spent two years at UCSD as a post-doc fellow and was intere
 sted in particular in understanding the molecular and cellular mechanisms 
 leading to peri-implant osteolysis. At that time the pioneered idea to use
  the orthopedic implant as drug delivery system and has since proposed dif
 ferent solutions relevant for clinical applications. In particular\, he co
 -founded a start-up (flowbone.com) to translate into a clinical applicatio
 n the development of an injectable hydrogel used to prevent osteoporotic f
 racture. From 2006 to 2013\, he was an Assistant Professor at EPFL and sin
 ce August 2013\, was appointed Associate Professor (with tenure) of Biomec
 hanics at EPFL. He is the director of the Laboratory of Biomechanical Orth
 opedics. His research topics include biomechanics of the musculoskeletal s
 ystem\, mechanobiology in bone and cartilage\, drug delivery system for bo
 ne and cartilage\, functional tissue engineering. His close collaboration 
 with different hospital departments has resulted in research output orient
 ed toward applications.\n\n\nZoom link (with registration) for attending r
