Apart from many papers in prestigious journals, he has written two books.Dr. Jayanta Bhattacharya is a Professor in the School of Environmental Science and Engineering and a Professor of Mining Engineering at Indian Institute of Technology, Kharagpur , He is the founding Head of the School of Environmental Science and Engineering, Indian Institute of Technology Kharagpur. Prof. Bhattacharya is a famous scientist in the area of environmental technology and product development. Prof. Bhattacharya pioneered research of laboratory and wetland schemes of wastewater treatment as a constructed plant based systems what presumably one day bioremediation systems would look like and have the capacity to perform. A continuous theme of research by his team is to develop new technologies and products for green treatment options.

Kayal completed his M.Sc. in Applied Geophysics at ISM Dhanbad (1969) and a Ph.D. in Seismology from Victoria University of Wellington, New Zealand (1983). He spent decades researching earthquake seismology, micro-earthquake studies, and active tectonics and seismotectonics of the Indian subcontinent, particularly focusing on the Himalayas, northeast India, and adjacent plate boundaries. He served as Deputy Director General (Head, Geophysics) at the Geological Survey of India, and later as a CSIR Emeritus Scientist at Jadavpur University in Kolkata. His work has contributed to mapping crustal structure, aftershock sequences of major earthquakes (such as the 2001 Bhuj, the 1999 Chamoli, and 2004 Sumatra–Andaman events) and seismic hazard assessment in India.
