Bio

Dr. Akay started his tenure at Carnegie Mellon as a professor and head of the Mechanical Engineering Department in 1992. In 1997, he was awarded the endowed Lord Chair in Engineering.  Between 2005 and 2008, Dr. Akay served as the Director of Civil, Mechanical and Manufacturing Innovation Division at the National Science Foundation. Currently he is serving as Vice President and Professor, and founding head of the Mechanical Engineering Department at Bilkent University in Ankara, Turkey. Professor Akay has held visiting appointments at the MIT Aeronautics and Astronautics Department, the University of Rome "La Sapienza," and Institut National des Sciences Appliquées (INSA) de Lyon in France and other institutions. Dr. Akay continues to serve as a member of industry boards and regularly consults with international industries as a technical advisor and serves on advisory boards of several universities and government agencies including the US NSF - Taiwan NSC Summer Institute on Bio-inspired Sensing & Bio-inspired Actuation Technology. Professor Akay is an active member of the engineering professional community, and has been recognized for his contributions to research, education and professional service. Professor Akay is the recipient of the ASME Per Brüel Gold Medal (2005) and Humboldt Research Award (2011). He is a fellow of the American Society of Mechanical Engineers, a fellow of the Acoustical Society of America, and a member of several honor societies.

Research

Professor Akay’s research lies in applied mechanics with emphasis on vibrations, acoustics, tribology, and dissipation theories.  His earlier research that addressed impact and transient noise mathematically described conversion of energy associated with the acoustic mass to sound during transient motion. His work on fluid-layer damping later led to a discovery and visualization of streaming that develops within a thin fluid layer. Much of his current research focuses on friction-induced sounds and on contact damping. A current collaborative research project with the University of Rome applies the concept of thermalization of vibrations, inspired by the dynamics of atoms in a solid, to reduce vibrations in complex structures. This work is now extended to model dissipation in thermal baths that surround nano-scale devices. His current research with colleagues at INSA-Lyon focuses on measurement and modeling of parameters that can describe tactile sensation and wave generation between sliding surfaces.  Most recently, he has started a center on design and manufacture of microsystems at Bilkent University and is working on MEMS-based vector acoustic sensors.
