2018 CERS Keynote Speaker
Professor Ellen M. Arruda is a Professor of Mechanical Engineering at the University of Michigan. She also holds appointments in Biomedical Engineering and in Macromolecular Science and Engineering. Professor Arruda earned her B.S. degree in Engineering Science and her M.S. degree in Engineering Mechanics from The Pennsylvania State University, and her Ph.D. degree in Mechanical Engineering from the Massachusetts Institute of Technology. She joined the UM faculty in 1992.
Professor Arruda teaches and conducts research in the areas of theoretical and experimental mechanics of macromolecular materials, including polymers, elastomers, composites, soft tissues and proteins, and in tissue engineering of soft tissues and tissue interfaces. Her research programs include experimental characterization and analytical and computational modeling of soft materials, including native and engineered tissues. Her interests in tissue engineering include scaffoldless methods using primary and mesenchymal cell sources, tissue engineering of tissue interfaces such as the myotendinous junction, and enthesis and multi-phasic tissue engineering. Her polymer mechanics work has focused on the mechanics of these highly strain rate and temperature dependent materials with emphasis on the relationships among the structure at various length scales to the deformation mechanisms of those structures to predict the mechanical responses. Professor Arruda’s current research objectives in tissue engineering and tissue mechanics are the design and development of scaffold-free multi-component tissue structures with functional interfaces for use as grafts in soft tissue tears such as the anterior cruciate ligament (ACL) and the supraspinatus (rotator cuff) tendon. This research necessitates an extensive experimental program to characterize the non-linear, anisotropic, viscoelastic response of native and engineered soft tissues. Professor Arruda has developed a highly successful model for ACL repair that restores native anatomy and function within 6-9 months of implantation and has formed a start-up company to market this technology. Her work has recently earned several honors and awards including the Ann Arbor Spark Best of Boot Camp award 2012, the 2012 Excellence in Research Award by the American Orthopaedic Society for Sports Medicine, and the cover article in Tissue Engineering, January, 2012. She currently holds three patents for this work.
Professor Arruda’s goals in her current polymer mechanics research are the design and development of high-performance polymer nanocomposites with exceptional properties under very high strain rates of loading. Her work involves the design of nanoscale building blocks and molecular network nanostructures for high toughness materials and the use of these well-characterized nanostructural components to inform physically-based analytical and computational models. Professor Arruda has led a team of investigators in this work for the past seven years and recently the team earned the 2012 Ted Kennedy Family Team Excellence Award from the UM College of Engineering. Additional recent recognition for her teaching, research, and service contributions to the engineering enterprise include the 2015 Outstanding Engineering Alumnus Award from the Pennsylvania State University, the 2014 Distinguished Faculty Achievement Award, from the University of Michigan, and the 2014 Trudy Huebner Service Excellence Award from the College of Engineering, University of Michigan.
Professor Arruda has ~100 papers in scientific journals. Her H-index is 26 (ISI). Professor Arruda is a Fellow of the American Society of Mechanical Engineers, the American Academy of Mechanics, and the Society of Engineering Science.
Keynote Speech Title: An Eight-Chain Odyssey…
In this talk I will discuss my research journey, beginning with my work as an engineering science major at Penn State, followed by my MIT years, and concluding with my current research at Michigan. My current research interests include characterizing and modeling the soft tissues of the knee and I will describe some of the techniques we’ve developed for accurate and reproducible experimental characterization of the non-linear, anisotropic, poro-visco-elastic anterior cruciate ligament (or ACL). I’ll discuss how we develop material models based on the characterization and implement them into a computational framework for full-knee biomechanics simulations.
