素粒子物理学
Ahmad attended the doctorate school at the Université de Montréal and did a two-year-long course in Particle physics and engaged his research on theoretical physics. In 1959, Ahmad obtained D.Sc. in physics after submitting his doctoral works on concepts on advancing on particle physics. His theses were written in fluent French and English language, and he reluctantly returned to Pakistan under the terms of Colombo Plan contract. His DSc theses were supervised by and covered a wide range of research in the study of elementary particles by using the deployment of special fine grain nuclear emulsion (AgBr). During his long doctoral studies, Ahmad studied nuclear reaction at the Montreal Laboratory with supervisors and scientists role in the Manhattan Project. Upon his return to Pakistan, he joined the Pakistan Atomic Energy Commission (PAEC) as a senior scientist.
