Dr. M. Afzal

ASSOCIATE PROFESSOR
PROFILE SUMMARY

Dr. Muhammad Afzal is an applied mathematician with a strong interest in wave mechanics, specifically in modelling, analyzing, and applying wave phenomena in various scientific and engineering fields. Since obtaining his PhD in Mathematics from Quaid-i-Azam University in 2015, he has dedicated his research efforts to the broad area of applied mathematics, focusing particularly on the theoretical understanding of wave processes. Dr. Afzal research activities primarily revolve around the scattering of acoustic or electromagnetic waves from geometric or material discontinuities, which have wide-ranging applications in acoustics, elasticity, water wave theory, and electromagnetic wave propagation problems. He has extensively worked on the application and development of mode-matching methods and Non-Sturm-Liouville systems. Further, he has extended the mode-matching approach by incorporating Galerkin procedures, low-frequency approximations, and multimodal formulations. Dr. Afzal has published over 25 articles in high-impact journals and contributed a book chapter in a publication by the American Mathematical Society, USA. He is recognized as an approved supervisor by the Higher Education Commission of Pakistan (HEC) and has successfully supervised 4 PhD and 13 MPhil students.
