Research Focus: Research has involved retrieval analysis of ultra-high molecular weight (UHMWPE) components of total hip and knee arthroplasty as well as polyetheretherketone (PEEK) components of spinal devices. Current research interests include methodology development for the evaluation of modular tapers in total hip arthroplasty and data analytics to determine large scale medical device performance.

Research Focus: Investigate tribological and mechanical properties of UHMWPE, PEEK and UHMWPE/PEEK polymer composite materials for their use in total joint arthroplasty. Characterize PEEK wear debris and compare its properties with CoCr and UHMWPE wear debris. Inspect retrieved devices for taper abrasion and corrosion, and identify the prevalent causes.
