Surface science and tribology, hard coatings and thin films

Our research is in the area of surface science, tribology, design and characterization of hard coatings and thin films.  We are interested in understanding how surface interactions affect friction and wear, especially in different temperature and environmental conditions.  Our work in hard coatings focuses on the synthesis, characterization and applications of hard coatings in computer disk drives, dry machining, ultralow friction and various high-temperature tribological applications.  We are also designing thin films and materials with excellent infrared reflection properties, for use in automotive and aviation applications.
