My research program is focused on solving problems that involve materials, their mechanical behavior, and factors (either environmental or manufacturing) that influence their performance and durability. Our current studies are focused on understanding the properties of hard biological tissues, the engineered materials that replace them, and the interfaces between hard tissues and biomaterials. Much of the effort is aimed at evaluating the fatigue and fracture behavior of these materials, as well as finding ways to examine and quantify changes in their behavior with aging. Our methods extend from the nano- to the macro-scale. Some of our recent efforts have involved topics that are relevant to the fields of orthopedics and restorative dentistry. Though we address fundamental questions, the ultimate goal is to contribute to the pursuit and maintenance of lifelong health
