Dr. A. Rehman Kashif


Dr. Abdul Rehman Kashif completed his Ph.D. degree in the symmetries of spacetimes in General Relativity from the Quad-i-Azam University, Islamabad, in 2004. He has worked as a Postdoctoral fellow at the University of Aberdeen, Scotland, UK. He has vast teaching experience in undergraduate and graduate teaching in Mathematics. He has also represented Pakistan in many advanced countries to present his research work in academia. He is an HEC-approved supervisor and currently supervising MS and Ph.D. students. He is an active researcher in the field of Newtonian and Einstein Gravities. Currently, he is working on the N-Body Problem and restricted 5 or 6 body problems in Newtonian Mechanics and Gravitational Waves and Blackholes in Einstein’s Gravity.
