Prof. Gupta died in Kolkata on 14 June 2012 after suddenly taking ill.

Academic career

Gupta's doctoral thesis was done under the supervision of G. Bandyopadhyay at the Indian Institute of Technology Kharagpur in 1958. He further acquired a D. Sc. from the same institute in 1966.

He joined the faculty of IIT Kharagpur in 1957 as an associate lecturer and rose through the ranks to become a professor and subsequently, an emeritus. He was President of the annual Congress of the Indian Mathematical Society in 1999. He also served on the editorial boards of various scientific journals. He retired in 1993, but continued to be active in research.
