Mr. Nijesh P is a doctoral candidate in the Department of Geology, Centre for Advanced Study, Institute of Science, Banaras Hindu University, Varanasi, Uttar Pradesh. Nijesh specializes in hydrogeology. He is well-versed in hydrological field investigation, hydrogeochemical analysis, hydrogeochemical modelling, remote sensing and GIS, mineral identification and exploration, and geophysical survey. He has published papers in various reputed national and international journals. The most recent one deals with the study of isotopic characteristics and water quality with emphasis on fluoride in the water-scarce Lalitpur district of the Bundelkhand region in India.

Nijesh holds a master’s degree in Applied Geology from Anna University, Chennai, Tamil Nadu, where he passed with first class. He has worked as a Junior Research fellow at Banaras Hindu University, Varanasi, Uttar Pradesh, and Jawaharlal Nehru University, New Delhi, before enrolling into his doctorate program. He is a hodophile and loves to explore new destinations. He also has a keen interest in music and is an amateur guitarist.

Nijesh is pursuing a doctoral program on “Hydrogeological and Isotopic evolution of springs and their management strategies in a micro watershed of Kosi River basin at Kumaun Lesser Himalaya Uttarakhand, India.” He is widening his research data and inferences further at Penn State University through the Fulbright-Nehru Fellowship. The research opens a new door toward the methodologies and parameters used in hydrogeology for the study of springs.

Mr. Sourav Kumar is a Ph.D. student at the Department of Civil Engineering, Indian Institute of Technology Guwahati, Assam. His doctoral research focuses on the evaluation of earthquake-induced changes in groundwater composition, commonly known as hydro-geochemical earthquake precursors (associated with the slow accumulation of tectonic stress in the Earth’s crust) in northeast India.

Mr. Kumar obtained his bachelor’s degree in Civil Engineering at Uttarakhand Technical University, Dehradun, in 2016. He completed his master’s degree in Earth System Science and Engineering under the Department of Civil Engineering at the Indian Institute of Technology Guwahati, Assam, in 2018. He received the MHRD-GATE Fellowship for two years of his M.Tech. in 2016, where he studied the spatio-temporal variability in India’s groundwater storage using GRACE data. As his research expanded and segued into his doctoral research, he has presented his work at international conferences in 2019 and 2021.

As a Fulbright-Nehru fellow, his primary objective is to understand the links between earthquakes and hydrological/hydro-geochemical variation that could be used as basic scientific input required for an impending earthquake prediction at both national and international levels. The proposed study could be used to correlate datasets from northeast India with those from other parts of the world such as Iceland, Japan, Korea, Italy, China, and the United States, that have reported similar earthquake-induced changes in groundwater composition.

In addition to his academic engagements, he also led the cricket team of IIT Guwahati at the ‘All-India Inter-IIT Sports Meet’ during 2017-19 and held several student representative posts at the institutional level throughout his college years.
