The Team


Tom Andriacchi, PhD
Chairman of the Board & Co-Inventor of The KneeMo®

Tom Andriacchi PhD, an emeritus professor at Stanford University, is one of the founders of SomaTX Design and one of the co-inventors of The KneeMo®. 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.


Jenny Hledik, PhD
Co-Inventor of The KneeMo® and Advisory Team Member

Jenny Hledik is an Instructor at Stanford University in the Department of Orthopaedic Surgery and has over 15 years of experience in musculoskeletal research.  Her research focuses on understanding musculoskeletal injuries and the development of non-invasive interventions to treat them. She is co-inventor of The KneeMo®. Prior to her current role, Dr. Hledik has held positions as a Research Engineer at Stanford University and the Veterans Affairs Hospital, and as a clinical researcher at Solta Medical. Dr. Hledik earned her PhD and Masters of Science at Stanford University in Mechanical Engineering, and her Bachelor of Science in Mechanical Engineering at Penn State University.

President, SomaTX Design, Inc.

Timothy T. Wulf is a retired Assistant Professor of Economics & Business from Parkland College.   While teaching, Tim also coached basketball and developed an interest in Sports Medicine as his female athletes would experience sports related injuries.  Tim was inducted into the College Hall of Fame in 2010.

A serial entrepreneur, Tim has partnered and initiated 4 successful start-ups in retail pharmacy, financial planning, a franchise restaurant and real estate before helping to found SomaTX Design, Inc.  Tim serves as CEO and President of the company.


Linda Wulf
Secretary Treasurer, SomaTX Design, Inc.

Prior to SomaTX Design, Inc., Linda Wulf wore many hats including Directing an Illinois Foodbank, CFO of a gymnastics franchise, collections supervisor for a medical device company, overseeing the operations, accounting, computer systems, scheduling, payroll and human resources of 3 retail restaurants with 100 employees.  During a brief break in the action, she took up snow skiing and had skiing accident shortly thereafter.  Fortunately, her mentor and friend’s husband was working on the The KneeMo®  prototype at the time and Linda had the opportunity to wear and test the original device during recovery.  As CFO, Linda provides operational support to the CEO, she manages SomaTX Design, Inc.’s finances, computer information systems, accounting and contract manufacturing.

Arielle Fischer, Ph. D
Advisory Team Member

Arielle Fischer PhD is an Assistant Professor at the Technion- Israel Institution of Technology in the Department of Biomedical Engineering and is the head of the Biomechanics & Wearable Technology Lab. Arielle made her way out to California for her post doctorate at Stanford University during which she led the first clinical trial of SomaTX’s The KneeMo®. Arielle’s expertise focuses on designing, developing, and manufacturing biomechanical interventions including smart wearable devices that treat osteoarthritis, soft tissue injuries and muscle-skeletal dysfunction. Prior to SomaTX Arielle worked on several interventions for improving joint motion and loading patterns including body weight unloading devices and orthotics. Arielle studied for her BSc in Biomedical Engineering at MIT and Technion and holds an MSc and PhD in Mechanical Engineering from the Technion.


Jessica Asay
Advisory Team Member

Jessica Asay is a research engineer with the Stanford BioMotion Laboratory and the Palo Alto Veterans Affairs Hospital, with over 14 years of experience collecting and analyzing human motion. Her research focuses on understanding the effects of knee pain while walking, understanding the effects of knee injury and osteoarthritis on knee joint mechanics, biology, and cartilage structure, and the testing and development of non-invasive treatments for knee osteoarthritis. Ms. Asay earned her Masters of Science in Mechanical Engineering from Stanford University and her Bachelor of Science in Mechanical Engineering from the University of Portland.
