Research Interests

Professor Polycarpou research interests include tribology, nanotechnology, microtribology related to miniature systems, magnetic storage, surface characterization, friction/vibration interaction, system dynamics and modeling, and experimental design and instrumentation. Specifically he studies micro/nanotribology of magnetic head disk interfaces and microelectromechanical systems. Recent emphasis has been on the tribology of devices for reduced energy and improved environmental-related impact, such as the use of carbon dioxide as a natural refrigerant and the use of surface treatments towards oil-lees machine operation. Polycarpou is the author of over 130 archival journal papers, numerous book chapters, volume proceedings, a dozen patents and numerous conference papers.
