Dr. Gangopadhyay was involved in R&D work of different types of optical fiber sensors such as Fiber Bragg Grating (FBG) sensors for smart structures, FBG sensors for Electrical Power line application, Fabry–Pérot interferometer (FPI) for vibration sensor, etc. He has also fabrication expertise of some fiber-optic components such as bi-directional couplers for any splitting ratio,

WDM couplers for 1550, 1310 and 980nm. His current research interests are the development of Bio-medical sensors, Fiber FPI Sensor, chemical sensor using Fiber loop resonator for cavity ring down spectroscopy (FLRDS), chemical sensor using photonic crystal fiber (PCF) and packaging of fiber-optic sensor, etc. He has authored 25 Nos. international refereed journals, three patents, Four Book Chapters, and 35 Nos conference contributions and proceedings at international conferences and meetings. He is a Senior Member of Optical Society of America (No. 951188). He has done some research work in SINTEF, NTNU, Norway, related to FBG sensor for On-line temperature monitoring of high voltage (400KV) overhead transmission lines for dynamic load regulation. Finally the setup has been installed on the Power Grid transmission in India for continuous three years measurement. He has done some research work as Visiting Scientist at CNR-Istituto Nazionale di Ottica Applicata (INO), Naples, Italy, on fiber-loop resonator, cavity ring down spectroscopy and absorption spectra of molecular gas/ liquid species. He has many projects with Foreign Bilateral Collaborations. Recently, he has also done some research work as Visiting Scientist in Kingston University, London and Maribor University, Slovenia. He is also acting as manuscript reviewer in many SCI journals.
