Throughout my career, my scientific research has been focused on the relationships between material processing, structure, and properties in structural materials. When a layperson asks me what I research, the short answer is: I make it, break it, look at it and make it better.
At the University of Washington my research covers a variety of materials (metals, ceramics, polymers and composites) with the common goal of improving structural properties by relating the processing to the microstructure and subsequent mechanical behavior. This approach has been successfully implemented in both basic scientific research and applied research with industry. Fundamental issues relate the strength and fracture behavior of materials to their processing technique and resulting microstructure. This behavior is often related to the characteristics and properties of the material surfaces and interfaces. The design and implementation of experimental techniques to measure material behavior for the development of materials models, e.g. constitutive laws, for computational modeling of material or component performance is often necessary.
Specific research projects included adhesive bonding of composites, fracture and fatigue of metallic nanolaminates, processing and properties of dental ceramics, mechanical properties of natural composites, nondestructive evaluation of thermal damage and surface analysis techniques for quality assurance of bonded structures.
