Dr. Saleem Nasir is a Postdoctoral Fellow in the Center for Catalysis and Separation (CeCaS) at Khalifa University of Science and Technology, Abu Dhabi, United Arab Emirates. He holds a PhD and MPhil in Applied Mathematics from Abdul Wali Khan University, Mardan, Pakistan, as well as an MSc in Mathematics from the University of Peshawar. With over 14 years of academic and research experience, he has authored more than 50 peer‑reviewed publications in international journals, with several additional manuscripts under review. Dr. Nasir’s research focuses on applied mathematics and computational modeling, particularly computational fluid dynamics (CFD), nanofluid flows, heat and mass transfer, magnetohydrodynamics (MHD), and nonlinear science. He has also worked extensively with artificial neural networks and machine learning to enhance predictive modeling in thermal–fluid systems. His technical expertise includes advanced use of ANSYS Fluent, COMSOL Multiphysics, EDEM, MATLAB, Mathematica, and Python. Prior to joining Khalifa University, he held a postdoctoral fellowship at King Mongkut’s University of Technology North Bangkok, Thailand, where he contributed to funded projects on nanofluid heat transfer and advanced thermal management. Dr. Nasir has been involved in several national and international research grants and actively serves as a reviewer for high‑impact journals in energy, thermal engineering, fluid mechanics, and applied mathematics.
