Prof. Ray graduated in Medicine from R.G. Kar Medical College, Kolkata in 1985. Subsequently, he did his post graduation in Anatomy from the Institute of Medical Sciences, Banaras Hindu University in 1988. He worked as a Service senior demonstrator at the same Institute upto March, 1991. Prof. Ray shifted to the All India Institute of Medical Sciences at New Delhi as senior demonstrator, where he was appointed to the faculty post in September, 1993. He has supervised the research work of several undergraduate and postgraduate students.

His research interest centers on mechanisms of pain, particularly at its site of initiation as for example following surgery, trauma or extensive tissue damage as in burn injuries. Recently, several prominent personalities (like N. Richards & S.B. McMahon, King’s College, London, UK) in the field of pain have hypothesized about the local treatment of pain. Hence, in his laboratory, antinociception following peripheral intrawound administration of analgesic drugs like the inhibitor of inducible nitric oxide synthase is being studied. The results could open up a novel way of treating pain as central side effects could be avoided, dose of the drug would be very less and even the antinociceptive effect comparatively higher because pain is being treated at its site of origin. He learned intrathecal catheterization in rodents under the tutelage of Prof. Tony Yaksh, who first demonstrated it in 1976.  Several independent research projects from the Department of Biotechnology and Indian Council of Medical Research were awarded to him.
