Dr. George Joseph started his research career in 1962 at the Tata Institute of Fundamental Research (TIFR), Bombay. A novel detector system designed by him was flown on the first Indian Satellite ARYABHATA to detect solar neutrons. Since 1973, at Space Applications Centre (SAC), he was instrumental in de¬veloping a variety of electro-optical sensors for earth observations, first of its kind in India. He is rightfully considered the pioneer of satellite based imaging sensors in the country.

Dr Joseph has served in a number of national and international committees/organisations including President of Technical Commission–1 of the ISPRS during 1996-2000. He has published a number of scientific papers in national and international journals. He has authored a book titled `Fundamentals of Remote Sensing’, a complete textbook on remote sensing written by an Indian author for beginners. He is fellow of a number of national academies like the Indian Academy of Sciences, National Academy of Sciences, and the Indian National Academy of Engineering. He has been honoured with Padma Bhushan in 1999. He is the recipient of the distinguished Bhaskara Award and several awards for his contribution to the field of remote sensing technology and application
