Education

Born in Jhelum, Punjab, Khan received his intermediate education from there and attended University of the Punjab in 1964. He received his B.A. in mathematics in 1966. The same year, he was admitted to the graduate school of the Punjab University, and did his M.A. in mathematics in 1968. With an awarded scholarship in 1974, he traveled to Great Britain to pursue doctoral studies in mathematics. He attended University of Wales at the Aberystwyth where, in 1977, he wrote his doctoral thesis on "The Strict Topology and its Generalizations" which was supervised by Dr. K. Rowlands. Following his thesis, he was awarded his Ph.D. in mathematics in 1977^[2]

Academic career

He joined Government College, Pattoki in 1968 where he served as a lecturer. In 1971, he moved to Islamabad and joined Federal Government College as a lecturar. After his Ph.D. in 1977, he again joined Federal Government College Islamabad as a Lecture, and a visiting professor at the Quaid-i-Azam University Islamabad. In 1981, he went to Libya where he joined Garyounis University Benghazi as an assistant professor. After spending five years there, he came back to Pakistan and re-joined Federal Government College Islamabad in 1986. In 1991, he joined Qaid-i-Azam University as an associate professor. In 1996, he went to Saudia Arabia where he joined King Abdulaziz University Jeddah, as an associate professor. In 2003, he was upgraded to his position and serving as a full professor of mathematics at there.

Academic Research

He is a noted researcher and has published monograph on "Topological Vector Spaces of Continuous Vector-valued Functions". He joined International Center for Theoretical Physics (ICTP) as a visiting mathematician in 1990s. He has taught undergraduate and post graduate mathematics. He has been engaged in the research to the fields of Linear topologies on spaces of continuous vector-valued functions, Stone-Weierstrass approximation theorem, Best approximation, Vector-valued measures and integration, Fixed point theorems, Topologies on topological algebras and topological modules, Multipliers, derivations and homomorphisms.^[3]
