His field of expertise is materials science and engineering. He conducts implant failure analysis of total joint replacements and particle characterization at the Biocompatibility and Implant Pathology Laboratory and the Tribology Laboratory at Rush. His current research focuses on corrosion within modular taper junctions of total hip replacements and how corrosion products affect the patient. His Cohn Fellowship project will use infrared spectroscopic imaging and Raman spectroscopy to detect and characterize wear and corrosion products from total hip replacements within periprosthetic and remote organ tissue.
