报告摘要：

Joining of dissimilar materials is a fundamental challenge in engineering.  Nature presents a highly effective solution at the attachment of tendon to bone  in the rotator cuff of the shoulder’s humeral head. The natural attachment is far superior to that which exists following healing or surgical repair: the natural attachment does not regrow, and recurrence of tears following surgical repair is as high as 94%.  My collaborators and I study how the natural tendon-to-bone attachment functions and heals, and how healing might be improved through engineered solutions. Although much of the basic physiology is still debated, it is clear that hierarchical nanoscale-to-milliscale toughening mechanisms are central to tissue resilience, and that mechanical factors play a central role in developing and sustaining these mechanisms. This talk will focus on rolls of randomness in resilience of the otherwise highly ordered tendon-to-bone attachments, and will conclude with a brief overview of 3D strain mapping techniques we are developing for the purpose of detecting the health of some of these stochastic toughening mechanisms in patients who present with shoulder injuries.  

报告人简介： 

Guy M. Genin studies interfaces and adhesion in nature, physiology, and engineering. His current research focuses on interfaces between tissues at the attachment of tendon to bone, between cells in cardiac fibrosis, and between protein structures at the periphery of plant and animal cells.  He is a professor in the Department of Mechanical Engineering and Materials Science at Washington University, and in the Department of Neurological Surgery at the Washington University School of Medicine. His training includes B.S.C.E. and M.S. degrees from Case Western Reserve University, S.M. and Ph.D. degrees in applied mechanics and solid mechanics from Harvard, and post-doctoral research at Cambridge and Brown. Prof. Genin is the recipient of several awards for engineering design, teaching, and research, including a Research Career Award from the National Institutes of Health, the Skalak Award from the American Society of Mechanical Engineers, Professor of the Year from Washington University, the Yangtze River Scholar Award from the Chinese Ministry of Education, and best paper awards from several conferences and journals including the American Society of Mechanical Engineers’ Journal of Biomechanical Engineering.  He serves as co-lead of the NIH working group on integrated multiscale biomechanics experiment and modeling and currently serves on the editorial boards and as an editor, guest editor, or associate editor of a number of leading journals, including Proceedings of the National Academy of Sciences, ACS Biomedical Materials and Engineering, Acta Mechanica Sinica, and ASME Journal of Nanotechnology in Engineering and Medicine.
