  Academic Identity

Dr. N.C. Mondal received B.Sc. Physics (Hons.) degree from The University of Burdwan, West Bengal, and M.Sc. Tech. Geophysics from Banaras Hindu University (BHU), Varanasi. He obtained his Ph.D. in Geophysics from Osmania University, Hyderabad and also pursued an Advance Groundwater Modeling Study at Texas A&M University, Texas, USA under the BOYSCAST Programme (funded by DST, GoI).

Presently Dr. Mondal is working as a Principal Scientist of Electrical & Heliborne Geophysics Group, CSIR-National Geophysical Research Institute, Hyderabad, India & holding Associate Professor of Physical Sciences, Academy of Scientific & Innovative Research (AcSIR). 

His principal research topics encompass groundwater exploration, hydrochemistry, aquifer modeling, and entropy theory in water resources. He has developed (1) an efficient & versatile technique for estimation of groundwater potential zones, (2) an Index called Saline Water Mixing Index (SWMI) for evaluating the relative degrees of saline water mixing, (3) a novel technique developed for estimating the natural backgrounds of groundwater pollution, (4) a new innovative entropy-based model for assessing natural groundwater reserve, and (5) also an interaction-based model for assessing the degrees of hydrogeological vulnerability.

Dr. Mondal has actively contributed to the Pilot Project on Aquifer Mapping (AQUIM) using combined ground and heliborne geophysical surveys and proved that a combination of electrical and electromagnetic investigations delineates the aquifer in sedimentary basin with certainty.

He has credited more than 120-Research Articles in International & Indian Journals (Google Scholar Citations: 3554, h-index: 31 & i10-Index: 66;; 20-Chapters in Books and 50-Technical Reports.
