Welcome everyone . I began my professional education in Computer Systems Engineering form NUST at EME College,  started my Masters in Computer Engineering again from NUST --- Half way in between proceeded to the University of Manchester for PhD on NUST scholarship --- and now back to NUST at SEECS as Assistant Professor in the EE Dept..... I am currently also leading the VISPRO reserach group at SEECS:
