Dr. Ouellette’s expertise is in assessing the biomechanical, materials, and clinical/patient factors that influence performance and outcomes in orthopaedic devices.  He has researched the performance of many different orthopaedic devices through interpretation of clinical data and studies, and through inspection of retrieved devices.  His lab work has also utilized electrochemical and mechanical testing of orthopaedic devices.  He has designed novel test methods for measurement of corrosion and micromotion at modular interfaces, and has expanded his expertise into mechanical test methods for women’s health products.  He also has experience with a wide array of materials characterization techniques, examining metallic and polymeric materials at the bulk and microstructural levels.

Dr. Ouellette’s personal practice at Exponent includes analysis of retrieved modular orthopaedic devices, and specifically identifying how biomechanical loading, implant design and materials factors combine with clinical and patient factors to lead to revision of implants. Employing surface characterization techniques in addition to measurement of material loss from bearing and modular interface surfaces, he has examined numerous devices across many major product lines, with a particular emphasis on modular and metal-on-metal total hip replacements. Dr. Ouellette is also active in mechanical testing techniques for medical devices, and has designed unique protocols and fixture systems for polymeric implantable devices and finite element model validation, as well as extensive standardized testing for polymeric devices and materials.

Prior to joining Exponent, Dr. Ouellette earned his Ph.D. in Bioengineering from Syracuse University working in the lab of Dr. Jeremy Gilbert.  In addition to his efforts to better characterize fretting corrosion processes of modular tapers, he developed and characterized novel thin film self-reinforced composite (SRC-) PEEK and UHMWPE for use in modular taper junctions to prevent the onset of mechanically assisted corrosion.  He developed a series of in vitro mechanical and electrochemical test methods to evaluate the performance of modular taper junctions modified with SRCs in comparison with traditional metal tapers, showing that their use prevented any onset of fretting corrosion at the taper junction.  He has also developed in vitro test methods to directly measure the seating mechanics of modular tapers in an effort to better characterize and predict their eventual fretting corrosion behavior.

Dr. Ouellette has published papers and presented talks and posters at a number of conferences in subjects ranging from total hip replacements, fretting corrosion studies, biomechanical testing, materials characterization, polymer processing, composite processing and characterization, microstructural and surface characterization, mechanical testing, and microscopy.
