Tom Andriacchi, PhD

President, Chairman, Board of Directors

Tom Andriacchi, PhD is a co-inventor of KneeMo™ He is an emeritus professor at Stanford University and is one of the founders of SomaTX Design The principles of The KneeMo® emerge from his experience that comes from more than 40 years of research on the biomechanics of the knee focused on solving clinical problems ranging from sports injury to osteoarthritis. His research at the intersections of mechanics and orthopedics has been translated to numerous practical solutions to clinical issues ranging from the design of total joint replacement for treating end stage osteoarthritis to a shoe design to reduce stress on painful knees while walking. In addition, he is the author of more than 220 original scientific papers, more than 500 abstracts and numerous book chapters. His research has been recognized by international awards from both engineering and medical societies as recently as 2019 with the Kappa Delta award from the Orthopedic Research Society and a Lifetime Achievement Award from the Osteoarthritis Research Society International in 2020.
