Research Interest

My research interests are to understand fundamental mechanisms of material behavior, and use that understanding to create new materials to solve problems based on materials performance and longevity.  My research is focused on biomaterials: both materials that are manufactured to be implanted in the human body, and understanding human tissues as materials.  The current studies in my lab concentrate on surface modifications to biomaterials to prevent wear and corrosion; micro- and nano-structural modifications to increase fatigue and fracture resistance; understanding the structure/function changes in human arteries that occur as a result of aging or disease, and responses to interventions used to treat heart disease.  Our pursuits range from fundamental discovery of behaviors to practical applications to diagnose and treat arthritis and heart disease.  Although the focus of the lab is on biomaterials and biomechanics, the fundamental mechanics of materials research we perform is also applicable to non-biological systems, for example fatigue and fracture of structural metals, polymers, and ceramics.
