MaryBeth Privitera
Dr. Mary Beth Privitera, M.Design, FIDSA, is internationally known as an expert in medical product design, specifically in the area of applied human factors. She is a Professor at the University of Cincinnati’s Department of Biomedical Engineering and works collaboratively among the Colleges of Medicine, Engineering and Design. She is a consultant to the medical device industry with expertise in user interaction design and human factors. Additionally, she serves as faculty and co-chair of the Association for the Advancement of Medical Instrumentation’s Human Engineering Committee.
As a Professor at the University of Cincinnati’s Department of Biomedical Engineering, she is a Co-Founder of the Medical Device Innovation and Entrepreneurship Program. Her previous academic appointments include industrial design and in the Department of Emergency Medicine.
She has worked on devices which are intended for use across the practice of medicine and in home health situations. Her current research focuses on applied ergonomics and design interpretation. She has conducted contextual inquiry studies throughout the hospital with results intended to inform the design of devices, including physiologic monitoring and clinical decision making, software-based tools including intraprocedural augmented reality. In addition, she currently has had research funding supported by the Gates Foundation and US FDA CDER Division. She is a Fulbright Scholar in collaboration with the University of Nottingham.
She has authored several peer reviewed articles and a books titled “Contextual Inquiry for Medical Device Design,” promoting best practices for phase zero medical device development. Her 2nd book, edited and written in collaboration with AAMI Human Factors faculty is titled “Applied Human Factors in Medical Device Design.” This book aims at bringing all references and best practices together in one resource compendium.
Rita Lin, MS, RAC
Rita has effectively managed medical device designs from concept to commercialization. She applies her technical and regulatory backgrounds to coordinate teams across multiple disciplines and departments. Rita has successfully led efforts to develop new digital health products while at Vigor Health, execute design modifications on spine devices while at Stryker, and help clear and approve hundreds of medical devices and combination products while at the FDA.
During her career, Rita has earned several certifications and awards, including the Stryker Innovation award, FDA Quarterly awards, Six Sigma Green Belt, and RAC. She is also expert faculty for the AAMI Human Factors for Medical Devices and 510k/De Novo training courses, and is a recurring speaker for the Human Factors and Ergonomics Society and Clemson University College of Engineering.
Rita graduated from Duke University with a Bachelor’s and Master’s degree in Biomedical Engineering.
