Professor Ares Rosakis ForMemRS

Ares Rosakis is an interdisciplinary engineer who invented multiple high-speed, optical and infrared diagnostic methods for studying dynamic fracture, shear localization and impact phenomena at all length and time scales, enabling his experimental discoveries of Intersonic fracture and delamination in composites and of Super-shear rupture in frictional geological faults. He pioneered the use of Laboratory Earthquakes and scaling to resolve paradoxes in earthquake science and to study earthquakes worldwide.


He is a member of the U.S. National Academy of Sciences, the U.S. National Academy of Engineering, the American Academy of Arts and Sciences, the Academy of Athens, the Indian National Academy of Engineering and three European academies. His awards include the von Kármán (ASCE), Timoshenko (ASME), Rudolf Kingslake (SPIE), William M. Murray (SEM), Eringen (SES), Auriel Stodola (ETH Zurich) and the Horace Mann (Brown University) medals and was named Commandeur dans l'Ordre des Palmes Académiques by the Republic of France.


After graduating from Athens College, Rosakis obtained his BA and MA degrees from Oxford University and his MSc and PhD degrees from Brown University.
