Professional experience


Since 2017: Materials consultant at Ettehad Lent Pishro Sanat. A leading-edge company in research and development of Copper-Free friction materials for auto-brake pads. I have been conducting a project to design and develop friction materials based on Copper-Free formulation.
 
Since 2014: Assistant Professor at Sahand University of Technology, Materials Engineering Department.
 
2012-2014: Laboratory Manager at Ettehad Lent Pishro Sanat. A recently established company with advanced technology in producing auto brake pads. I contribute to design, establish and imply various tests on the products.
 
2010-2012: Materials Consultant in 2 companies (Lola Khodro and Ettehad Motor) producing suspension, heating, windshield wiper and steering systems for the largest two Iranian automobile companies Iran-Khodro and SAIPA.
 
2005-2010: Post doctoral associate at Ecole Polytechnique Fédérale de Lausanne (EPFL) in the Framework of a european project ExtreMat
“This research activity is motivated by the need for highly efficient heat sink materials having a tailored coefficient of thermal expansion and a high thermal conductivity. To this end, we investigated the parameters that allow successfully manufacturing of metals (e.g. Cu, Al, Mg and Ag and their alloys) containing large volume fractions of synthetic diamond particles.”
 
2004-2005: Laboratory manager in Ring Khodro Pars company (RKP) producing gray cast iron engine piston rings
 
2003-2004: Lecturer at Sahand University (Tabriz), the courses given; Materials Selection, Metal Forming, Scientific and Technical Writing
 
2002-2003: Lecturer at Azad University in Tehran, the courses given; Heat Treatmenet, Phase Transformation, Physical Metallurgy
 
1993-2005: Materials consultant in 3 companies (Lola Khodro, Ettehad Motor and Bonyan Sanat Aval) producing suspension, heating, windshield wiper and steering system for the largest iranian car company Iran-Khodro
