Ares J. Rosakis (Άρης Ροζάκις, born September 12, 1956 in Athens ) is a Greek - American mechanical and aerospace engineer at the California Institute of Technology (Caltech).


Rosakis earned both a bachelor's and master's degree in engineering from Oxford University in 1978 . In 1980 another master’s degree followed and in 1982 a Ph.D. at Brown University . In the same year he received his first professorship (assistant professor) at Caltech, in 1988 he became an associate professor , and in 1993 he was given a full professorship. Since 2004 he has been Professor of Aeronautics and Mechanical Engineering, succeeding Wolfgang Knauss Theodore von Kármán . Visiting professorships led him to the École normal supérieure (Paris) and Oxford University.

Rosakis recognized as a leader in the area of dynamic material failure solid materials, composite materials and compounds. Using high-speed photography , real-time measurements of temperature fields close to dynamically developing cracks and adiabatic shear bands, as well as newly developed optical and dynamic infrared methods, he investigates ductile fractures . He is considered the inventor of Coherent Gradient Sensing Interferometry (CGS interferometry). Further work deals with cracks in heterogeneous materials and composite materials, especially under shear conditions, with the crack mechanics of earthquakes , with the reliability of thin films and with in-situ measurement technology at the wafer level.

Rosakis has (as of July 2018) an h-index of 60. He has both Greek and US citizenship.
