To this day, Qadir has made important and significant contributions to the fields of differential equations, theoretical cosmology and mathematical physics.

[3] As of 2023, he is working as a visiting professor at Abdus Salam School of Mathematical Sciences, Government College University, Lahore.

Qadir is author of the book "Relativity: An Introduction to the Special Theory" which has been translated in several different languages and is widely read by science students in colleges throughout Asia.

He has attended more than 100 International and National Conferences and Seminars in the fields of Mathematics, Physics, Economics and the History and Philosophy of Science.

Asghar Qadir comes from a family whose members played important role in the formative years of Pakistan.

His father, Manzur Qadir was a Pakistani jurist in 1960s and served as foreign minister in President Ayub Khan's cabinet from 1958 to 1962.

Asghar Qadir was born in Simla (now Shimla) of British Indian Empire in 1946 to a middle-class family.

[1] There, he worked in a complex mathematical applications arise in the theory of nuclear fission at the ISIS neutron source – a neutron scattering facility that mathematically studies the structure and behaviour of nuclear materials in a fission process.

[7] In 1986, Riazuddin invited Qadir to Trieste, Italy to join International Centre for Theoretical Physics (ICTP) where he carried out his research in special and general theory of relativity.

At ICTP, he taught the advanced course of differential equations, Special functions, Upper and lower bounds on Entropy and the Number Theory.

[7] In 1988, after researching at ICTP under Abdus Salam, Qadir re-joined Qau and became full professor of Mathematics.

[12] As part of his contribution, the Government of Pakistan conferred Qadir with civilian award, Sitara-e-Imtiaz, and earned the national fame.

He retired from NUST in 2019, and is currently affiliated with Abdus Salam School of Mathematics Sciences, GCU Lahore.
