He has been selected in Category A for the Research Productivity Award in 2015 by “The Pakistan Council of Science and Technology” and has been regularly awarded Research Incentive Awards and Performance Evaluation Awards from the University of the Punjab and PCST. He has obtained different research projects as a Principal Investigator from the University of the Punjab and Higher Education Commission, Pakistan. He has completed two NRPU research projects as Principal Investigator and Co-Principal Investigator funded by HEC. Due to his significant research, his name is among the top young researchers in Pakistan in the field of Mathematics. Dr. Zaeem is also involved in supervising M.Phil./Ph.D. students in the fields of geometry, relativity, and cosmology. He has mentored 06 Ph.D. and 24 M.Phil. scholars and has been supervising 3 M.Phil. and 4 Ph.D. students. Dr. Zaeem has also been involved in organizing various seminars and National and International Conferences on Gravitation and Cosmology at the University of the Punjab.
Initially, Dr. Zaeem worked on the solutions of non-linear partial differential equations and the study of inhomogeneous matter distribution of the Universe due to different fields, in particular, electromagnetic fields. He also studied the cosmos' dynamical instability issue and cavity formation with self-gravitating objects. Currently, he is investigating the alternatives to black holes and their stability problem with mathematical modeling in the background of different gravitational theories.
