Research Overview

My research is in the area of materials science and micromechanics, dealing mainly with the relation between macroscopic properties and microstructure. Mechanical properties are of primary concern, although thermodynamic properties, transport mechanisms and electronic, optical and magnetic behaviors are of interest also. Both theoretical (including computer simulation) and experimental investigations are emphasized.

Current topics include platinum nanowires and networks as fuel cell electrodes, whisker growth from tin coatings, spontaneous combustion processing of near shaped intermetallic compounds and mechanical properties of nanocrystalline materials. Other topics include localized testing such as impression creep using micron-sized cylindrical indenters to determine adhesion, work hardening, viscosity, and the kinetics of stress relaxation.

Most of my PhD students are working in industry: four at Xerox, three at MRL/ITRI in Taiwan, and one each at Kodak, G.M., 3M, ATT Laboratory, Dow, Shell Development, Sandia, Naval Research Laboratory, Inland Steel, United Technology, Delphi, Philips Electronics, Stoody and Gerson. Four of my students are in academia.
