[3] In 1987, Banerjee who was a student of Ballygunge Government High School[4] completed a Bachelor's Degree at St. Xaviers College, Calcutta in Physics (major), Chemistry and Mathematics.
[5] Via a PPARC fellowship, he worked as a postdoctoral fellow at Armagh Observatory between 1997 and 2000 on solar atmospheric dynamics using the SOHO spacecraft.
As well as a son named Arno Banerjee who studies Environmental Chemistry in University College Dublin.
[6] In particular, he has focussed on the propagation of wavs through the solar chromosphere and corona, including innovations in the technique of atmospheric magnetoseismology.
[7] He has also studied space weather and the solar dynamo[8] through long-term observations such as those provided by the 100-year synoptic data from Kodaikanal Observatory.
