Dr. Vali was born in Bojnourd, North Khorasan, Iran. He received undergraduate degrees in applied physics (Solid State Physics) from Shahid Beheshti University, Tehran, Iran (1992) and in Solid State Physics from Tabriz University, East Azerbaijan, Iran (1994). He earned a Ph.D. in Theoretical Condensed Matther Physics from Ferdowsi University of Mashhad, Khorasan-E-Razavi, Iran (2004). He then held faculty position at the Damghan University, Semnan, Iran.
His Administrative portfolio includes but doesn't limited to dean of school of physics, and vice president for administrative and financial affairs. He is currently vice president for education and postgraduate studies from 2016 and full professor of condensed matter physics in Damghan university.
His research area lies in the field of Investigation of electronic, dynamical and dielectric properties of materials, using density functional theory and density functional perturbation theory; Quantum transport in mesoscopic systems; Topological Insulators; Spintronics; Nanoelectronics;
