Research Interests

Microstructure, properties, and processing of materials; Variability in materials and processing especially as related to biomaterials and mechanics; Experimental design/robust design

Research Overview

My primary research interest has always been in the relationships among the microstructure, properties, and processing of materials. Quantification of microstructure (through techniques such as electron, atomic force, and optical microscopy) is the essential link in understanding how materials behave. Study of microstructure-property relationships tells us how materials "work" and how they can be improved. Processing studies allow this information to be put to practical use in fabricating materials with improved microstructures and, therefore, properties. In recent years this work has expanded to include studies involving biological materials and mechanics, especially the important role played by variability in these systems. Dealing with variability, in traditional engineering materials as well as biological applications, has also led me to a strong interest in experimental and robust design methods.
