Timothy Fisher, M.B. Ch.B.
Vice President of Research
Dr. Fisher received his medical degree from Leeds University in the United Kingdom in 1983, where he first worked clinically. He then came to the United States and spent 20 years in academia at the USC Keck School of Medicine in Los Angeles, achieving the rank of Associate Professor of Research. He then transitioned to industry and has been the co-founder or owner of several medical companies. As Chief Scientific Officer for Ceremed he led the company in obtaining ISO 13485 certification, CE mark, and FDA 510(k) approval for their first medical device, Ostene. This hemostatic product went from concept through all stages of design control (including product development and testing; manufacturing process design and validation; packaging and sterilization; and regulatory approval in both the U.S. and Europe) within the company’s first 18 months. Dr. Fisher spearheaded marketing the device, including establishing an international distribution network with a dedicated in-house sales team. Within a few years, annual sales surpassed $5 million. Additional products were developed for major medical companies, which saw the company’s core technology utilized in more products approved for use in the orthopedic and spine markets of the U.S. and Europe. This gave Dr. Fisher a unique opportunity to develop partnerships with major companies in developing a variety of medical devices. The success of the product lines led to Ceremed being acquired by Baxter Healthcare. In early 2014, Dr. Fisher founded NeoMatRx, as a research and development company leveraging his expertise of working through the full product design lifecycle. He worked with customers to develop their products all the way from initial concept, through manufacture and regulatory approval, to market, with multiple products focused on the military trauma market. With expertise in the fields of medicine, device development, chemistry, and life sciences, Dr. Fisher then transitioned to Vice President of Research for Critical Innovations, where he plays a pivotal role in all aspects of medical product research, development, and commercialization.
