• Head, J. Mike Walker '66 Department of Mechanical Engineering
  • Meinhard H. Kotzebue '14 Professor
  • James J. Cain Chair in Mechanical Engineering
Andreas A. Polycarpou

Educational Background

  • Ph.D. Mech. Eng., State University of New York at Buffalo (SUNY) 1994
  • M.S. Mech. Eng., State University of New York at Buffalo (SUNY) 1992
  • B.S. Mech. Eng., State University of New York at Buffalo (SUNY) 1990

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.
