Dr. Day has a broad knowledge base in medical device R&D, design controls, products liability, and intellectual property, specializing in orthopaedic devices and the musculoskeletal system. Dr. Day analyzes the in vivo performance medical devices including evaluating retrieved devices to determine which patient, device, and surgical factors may have contributed to the need for revision. Dr. Day provides technical analysis for patent infringement and validity including inter partes reviews. He also consults in the area of radiographic and medical imaging at both the macro and micro scales, as well as in medical image processing.

Dr. Day is an active member of the Orthopaedic Research Society and is the Task Force Chair for the ASTM Total Shoulder Test Methods for the Arthroplasty Subcommittee. He currently holds an appointment as a Part-Time Research Assistant Professor at the Department of Biomedical Engineering and Health Systems at Drexel University. His research interests include biomechanics of the implant/tissue interface, specifically bone remodeling and the relation between bone strength and its structure. Prior to joining Exponent, Dr. Day has performed research at the Erasmus Medical Center in Rotterdam, The Netherlands, Rush University in Chicago, IL and at both the Institute for Experimental Clinical Research and the Orthopaedic Research Laboratory of Aarhus University in Denmark.
