User talk:TARUN KUMAR GANGOPADHYAY

Dr.Tarun Kumar gangopadhyay (TKG) was born in Gopalpur, West Bengal,India in 1959. He graduated bachelor of electrical engineering with first class in 1989 and master of electrical engineering in 1991 with first class,both from Jadavpur university, culcutta, India.

He carried out research in the area of 'Fiber Optic Transducers' in his thesis submitted for master degree. He joined in the Dishergarh thermal power station, India, working in the area of 'power generation and transmission'. Later he was appointed as electrical engineer in Central Glass and Ceramic Research Institute(CSIR), India. There he carried out research work in the area of 'development of varistor materials for high-voltage applications'.

During 1995-1999, he went to Australia in AusAID scholarship for commonwealth countries and there he was involved in the research and development of optical fiber vibration sensors for electrical power industry with high power Testing and Optical Fiber Sensors Group, School of Electrical and Information Engineering, The University of Sydney, Australia. He worked there in the field of intrinsic and extrinsic single-mode fiber based sensors and fiber-optic interferometry. He has got many awards and prizes for his research work from The University of Sydney and Australian Photonics.He visited many countries for attending International conferences

One of his great achievement is 'Fiber optic sensor for real-time monitoring of temperature on high voltage(400KV)power transmission lines', after calibration the sensor system was assembled and installed at a power station in the vicinity of subhasgram, Kolkata operated by Power Grid Corporation, India for a complete measurement of temperature.

Now he is working on fiber optic chemical sensor with a collaboration of CNR-Instituto Nazionale di Ottica(INO), Naples, Italy.

Currently he is working as a scientist E-II[Gr.IV(4)] In Central Glass and Ceramic Reaserch Institute(CGCRI).
