After receiving his PhD, Roy taught at the University of Kentucky for a short time and then returned to India where he was first at I.I.T. Delhi and then at Himachal Pradesh University in Shimla. Soon he got a fellowship at the Institute for Advanced Study in Shimla. After spending two years at the institute, he joined the Mathematics Institute at Punjab University as a Reader. Soon he returned to the US at SUNY Plattsburgh. In 1982, he joined Beloit College and spent the rest of his career there.[2]

Publications

Roy has published many papers on differential equations, fluid mechanics, special functions, Fuchsian groups, and the history of mathematics. He authored three advanced mathematics books: "Sources in the development of mathematics" (2011), "Elliptic and modular functions from Gauss to Dedekind to Hecke" (2017) and "Series and Products in the Development of Mathematics" (2021) all published by Cambridge University Press. He is a coauthor of the well-known book "Special Functions" (with G. E. Andrews and R. Askey), published by Cambridge University Press in 1999.[3]
