Research Statement

My research program is focused on solving problems that involve the mechanical behavior of materials and factors (either environmental or manufacturing) that influence their performance and durability. Our current studies are focused on understanding the properties of natural materials and engineered materials, as well as 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. Recent efforts have involved topics relevant to the fields of orthopedics and restorative dentistry. We address fundamental questions, with the ultimate goal being to contribute to the pursuit and maintenance of lifelong health.

In addition to our efforts on existing materials, we are developing new materials inspired by biological structural materials. We have current studies underway aimed at the development of bioinspired ceramics, metals and polymers for various applications with multi-functional performance and exceptional properties.
