Hamed Owladeghaffari

Postdoctoral Associate

Hamed O.Ghaffari joined Matěj Peč’s research group in June 2017. Hamed finished his PhD from the department of Civil Engineering (University of Toronto, 2014). From 2009 to 2010, he was a research assistant in university of Ottawa (Canada) , studying coupled process (THM) and gas propagation in deep geological repositories. From 2010 to 2015, He involved in Paul Young’s Lab.-University of Toronto- working mainly on ultrasound probes of fractured rocks under different conditions of stress and temperatures, including  micro-mechanisms in true triaxial tests ,rupture mechanism and dynamic loading tests. He was a post-doc (2015-2017) in W.A.Griffith’s Lab (University of Texas) and working on the response of materials under dynamic loading and out-of –equilibrium physics of micro-cracks with excited acoustic signals.

His current research includes study of acoustic phonon emissions to analysis physic s of partly molten rocks and lattice preferred orientations akin to mechanisms in upper mantle and with applications on deep-earthquake faulting.
