Biography

I gained PhD (Theoretical Physics) in 2007 working under the supervision of Prof. Dr. Du Ming Li, Institute of Theoretical Physics (ITP) Beijing China under Higher Education Commission (HEC) Basic-sciences scholarship program. During PhD study, I succeeded to formulate Theoretical Imaging Method (TIM) and Two-center Model, new theoretical tools to understand negative ions photo-detachment nearby different surfaces. After PhD, I joined the Department of Physics, COMSATS Islamabad University (CIU) Lahore Campus in 2007 as an Assistant Professor. Subsequently I joined the Centre of Excellence in Solid State Physics (CSSP), University of the Punjab in 2009 as an Assistant Professor on TTS. In 2014, I have been promoted to Associate Professor through BOG selection, keeping in view my extra ordinary performance at the Centre of Excellence in Solid State Physics. I am running a material simulation research group where structural, optical, magnetic, elastic, mechanical, vibrational and thermodynamic properties of different crystals are being investigated.
