Research Area
Dr. Saroj Kumar Mondal received his B.Sc. and M.Sc. degree in Physics from Vinoba Bhave University, Hazaribagh. Dr. Mondal obtained his Ph.D degree in Applied Geophysics from Indian School of Mines, Dhanbad. He has been working as a Scientist in CSIR-National Geophysical Research Institute, Hyderabad since 2014. His research interests include crustal strain rate variation, crustal stress change using GNSS (Global Navigation Satellite System) data and earthquakes data for understanding the probable zone of high seismic hazard for future large size earthquakes in Himalayan arc. He has expertise in GPS (Global Positioning System) site selection, construction of GPS stations, installations, data acquisition, data processing and interpretations. He also utilizes statistical tools for precursory signature of large size earthquakes globally. His active interest in field work has made him move to tough terrain throughout the country and abroad. He has established many GPS observatories in different parts of the country viz. Assam, Nagaland, Meghalaya, Minicoy Island, Jammu and Kashmir etc. He has dynamically participated in many geophysical data acquisitions viz. airborne LiDAR (Light Detection and Ranging) survey data in Koyna-Warna region, GNSS and Seismic data acquisition in Antarctica, Andaman & Nicobar Island for earthquakes study. He also worked in “Land Subsidence Study in Jharia Coal Field using GPS and InSAR Techniques”. He enthusiastically participated as a summer team member in 34th Indian Scientific Expedition to Antarctica (ISEA), 2014-2015. He had the opportunity to attend “Workshop on Quantification of Seismic Hazards in the Indo/Asian Collision Zone” held in Kathmandu, Nepal in 2012, organized by International Centre for Theoretical Physics (ICTP), Italy. Dr. Mondal has a good number of publications in peer reviewed national and international journals of repute and also presented his research findings in various national and international seminars /conferences.
