Research
Areas
My research program is focused on solving problems that are commonly at the intersection of solid
mechanics, materials and manufacturing processes. A large part of our current efforts are focused on understanding the properties of hard biological tissues,
the engineered materials that replace them, and the interfaces between them. Our studies are aimed at understanding the fatigue and fracture behavior of
these materials and systems, as well as finding ways to both characterize durability and extending it. Some of our most recent efforts have been in the
fields of orthopedics and restorative dentistry and have focused on the influence of existing treatment modalities on the mechanical behavior of hard
tissues and lifelong health. Support for our investigations comes from a number of organizations.
We also address the effects from manufacturing processes on the mechanical properties and structural integrity of conventional,
advanced engineering and biological materials. While not limited to machining, the laboratory has a primary focus on material removal processes and their
contribution to the short- and long-term component performance, health, and safety issues. The laboratory is well equipped to investigate fundamental issues
related to machining and material removal, and to solve research and development problems of industrial relevance.
