Peretz P. Friedmann is currently the François-Xavier Bagnoud Professor in the Aerospace Engineering Department at the University of Michigan , Ann Arbor . He is also the Director of the FXB Center for Rotary and Fixed Wing Air Vehicle Design, and the Associate Director of the Vertical Lift Research Center of Excellence (VLRCOE) which is a partnership between Georgia Tech (lead university), University of Michigan , Washington University in St. Louis and Utah State University .He has been with the University of Michigan since January 1999. Between 1972 and 1998 he was a Professor (1972-1977 Assistant Professor, 1977-1980 Associate Professor, 1980-1998 Professor) in the Mechanical and Aerospace Engineering Department of the University of California, Los Angeles. Between 1988 and 1991 he served as the Chair of the Department. He recieved his B.S. and M.S. degrees in Aeronautical Engineering from the Technion - Israel Institute of Technology and his Sc.D. (1972) in Aeronautics and Astronautics from the Massachusetts Institute of Technology. Prior to entering the Academic world, Dr. Friedmann was a Senior Engineer at Israel Aircraft Industries and an engineering officer in the Israeli Air Force.

Dr. Friedmann has been engaged in research on rotary-wing and fixed wing aeroelasticity, active control of vibrations, hypersonic aeroelasticity and aerothermoelasticity, structural optimization with aeroelastic constraints, aeroelastic scaling as well as wind turbine and jet engine aeroelasticity. He has published extensively, 294 journal and conference papers. A total of 31 Ph.D. students have graduated, under his mentorship, several of them hold faculty positions as well as senior positions in the aerospace industry in the US. He was Editor-in-Chief of Vertica-The International Journal of Rotorcraft and Powered Lift Aircraft (1980-90), Associate Editor of the Jouranl of Fluids and Structures (1997-2003), Associate Editor of the Journal of the American Helicopter Society (2004-9), and the AIAA Journal of Aircraft (2005-9). Since January 2009 he is the Editor-in-Chief of the AIAA Journal. He has also served on a number of national award boards and review committees engaged in review of research funding, as well as review of Aerospace Departments. He has been a naturalized US citizen since 1977.

Professor Friedmann has made lasting fundamental original contributions to rotary and fixed wing aeroelasticity, active control, optimization and unsteady aerodynamics that had significant influence on air vehicle design. His pioneering contributions in rotary wing aeroelasticity combined with his work on optimization of helicopter blades for vibration reduction had a major influence on the understanding of aeromechanical behavior and design of modern rotorcraft systems. Professor Friedmann's more recent work was instrumental in demonstrating that the actively controlled flap is the most promising device for active vibration and noise control in rotorcraft. He was the first to conceive the use of actively controlled flaps for vibration reduction in rotorcraft in 1990. Since then numerous researchers have been working on the practical implementation of this approach on current rotorcraft. During the last decade, his research on hypersonic aeroelasticity and aerothermoelasticity has made a major contribution towards understanding this important problem that represents one of the last frontiers in aeronautics. His accomplishments have been recognized with several awards listed below.
