Professor Viqar Uddin Ahmad has been associated with the HEJ Research Institute of Chemistry since its establishment in 1967. Prof. Viqar's currents interests are on isolation and structure elucidation of new natural products. Some of them have interesting biological activities. For example: VArious eudesmane sesquiterpenes which showed antibacterial activity against Escherichia coli, Klebsiella ozaenoe, K. pneumonieae, Proteus vulgaris, Shigella boddi, Staphylococcus aureus, S. pyogenes andB. anthracis; some triterpenoidal and steroidal saponins exhibited toxicity in Brine Shrimp Lethality bioassay and antibacterial activity against Pseudomonas pseudomaliae, Co-rynebactterium xerosis etc. One of the saponins isolated from a Trukish plant manifested hypotensive activity in anaesthetized rat.

Prof. Viqar Uddin Ahmad availed a Fulbright Fellowship of nine months in 1993. during his stay at Cornell University, Itacha, USA. Prof. Viqar Uddin Ahmad worked on the twelve step total synthesis of and alkaloid isolated from an insect. Prof. Viqar also dilivered lecturers in the chemistry departments of Central Michighan University, Michighan, Georgia Tech, Atlanta, georgia, State University, Atlanta, Georgia and Cornell University, Ithaca.
