The Team Behind Simbex

Richard M. Greenwald, PhD, founder and President, is an entrepreneur and biomedical engineer with over 15 years of experience in research and development in sports and orthopedic biomechanics.

Dr. Greenwald has been directly involved in product development for numerous biofeedback and data acquisition products for the medical and rehabilitation industries. He has received multiple awards from the National Institutes of Health, National Science Foundation, and Department of Defense for product development through the Small Business Innovation Program (SBIR). Dr. Greenwald previously started and managed the US Division: Orthopedics, Sports, and Rehabilitation, for TÜV Product Service, a multinational firm specializing in product testing and regulatory certification of products for sale in the European Union. He has significant key relationships with major US and international clients in the orthopedic, sports and rehabilitation fields. He currently serves on the Advisory Board for the National Center for Medical Rehabilitation Research at NIH.

He is an Associate Professor (adjunct) at Thayer School of Engineering at Dartmouth College.

Dr. Greenwald is currently directing four federally funded research projects at Simbex.

Dr. Dean is not only a world renowned fluids engineer with an impressive history of entrepreneurial successes, but he has a personal interest in prosthetics beyond the academic — as a transfemoral amputee for 60 years. Convinced that there must be solutions to the every-day annoyances that all lower-limb amputees experience, he has devoted much of his time and attention to solving them. Dr. Dean has been working on and testing the Active Contact System for almost a decade.

A MIT graduate (ScD — 1954) and MIT assistant professor (1951-56), he is now Professor of Engineering (Adjunct) at Thayer School of Engineering at Dartmouth College, a member of the National Academy of Engineering (1977) and a Fellow of ASME. He is President of Synergy Innovations, Inc., Lebanon, New Hampshire. He holds 18 U.S. patents. Dr. Dean received one of the first "Tibbett's Pioneer Awards" in recognition of his contributions to the Small Business Innovation Research (SBIR) Program. He was awarded the 1996 ASME Gold Medal for his many contributions to the engineering profession. In 1998, The New Hampshire High Technology Council awarded Dr. Dean the Entrepreneur of the Year Award.

Dr. Dean is founder or co-founder of eight companies: Creare Inc. (contract R&D in the thermal/flow sciences), Hypertherm Inc. (technology leader and world's largest manufacturer of plasma-arc metal cutting equipment); Creare Innovations Inc. (xerography and motion control) (now Spectra Inc., four color, hot wax, drop-on-demand printers); Verax (production mammalian-cell culture systems); Synosys (now PerSeptive Biosystems, Division of Perkin-Elmer, biotechnology instruments and process equipment); Synergy Research Corporation; Synergy Innovations, Inc. and Simbex (biomedical engineered products).

Jeffrey J. Chu blends a long history of applied research and product development in exercise science, sports and orthopedics to his position as Director of Engineering. His innovative algorithms based on neural networks, fuzzy logic, and advanced optimization techniques, along with a strong balance of electronic design, material selection, and software systems integration, keep the Simbex team driving toward new product solutions. Jeff has worked for sports product development companies ranging from Nike to New Balance and later Saucony, where he was responsible for developing advance concept motion control and shock attenuation technologies.

David W. Bertoni brings to Simbex years of management and senior management experience, an international perspective and an impressive record of strategic product launches. Bertoni spent 15 years at the sports marketing power adidas/Salomon. While posted at the company's French headquarters, he was responsible for product development and international marketing for the alpine binding and boot divisions and managed the worldwide launches of strategic products.

Mr. Bertoni has served as CEO and chairman of the Internet supply portal The Buyer's Page and Vice President — Sales and Marketing for Poseidon Technologies, a French-based computer vision company.

In 2000, Dave Bertoni and industry veteran Jackson Hogen founded Integrated Training Solutions, an employee development consulting company, which serves leading sporting goods retail and resort clients.

John Stephens has helped build several venture-backed firms from very early stages. As senior technical executive, he has set company direction in diverse markets including network communications, financial analysis and prosthetics.

Recently, John served as VP of Product Development for iWalk, a MIT spinoff developing robotic prosthetics. Prior to that, as CTO of Accentus, he developed a data monitoring system for the financial services industry based on the novel use of music as "aural graphing".

In 1986, John was one of 5 founders of Cayman Systems, an early innovator in cross-platform workgroup routers. As CTO, he set the technical direction of the company as it refocused on home broadband routers. In 2001, Netopia Inc. (recently purchased by Motorola) acquired Cayman. As Netopia's VP of Broadband Services, John integrated several internal development groups and acquisitions to create a family of value-added broadband services, including one licensed to the Linksys division of Cisco.

John graduated from Williams College with a degree in Economics and received an MBA from MIT's Sloan School of Management.

Aaron T. Buck has directed the business activity, development, and early production of Simbex's HIT System™ technology for the last two years. Prior to accepting this role, Mr. Buck was project manager for the successful North American launch of the Active Contact System™, the first commercial product offering from Simbex. Possessing strong abilities in mechanical and optimization analysis, materials processing, and design for manufacture, Mr. Buck has been instumental in the realization of ideas through management of the Simbex product development process. These traits are a perfect fit with Simbex methodology, which uses rapid protytyping and testing to move technical ideas through validated proof of concept and subsequent manufacture.

Aaron received a Masters degree in Engineering Management from the Thayer School of Engineering at Dartmouth College. Prior to joining Simbex, he was active in the areas of both metallurgy research and advanced engineering for motor sports. During his time at Thayer School, Aaron served as director of Dartmouth Formula Racing, a student-run organization that competes annually in Formula SAE, a worldwide engineering competition dedicated to the design, fabrication, and driving of Formula-style racecars.
