An applied hydrogeologist /Geologist having a dynamic career with more than 14 years of experience
in various aspects of soil, groundwater and environmental investigations, assessment remediation and
management projects and programs. He has hands on experience in the design and supervision of
hydrogeological investigations to determine aquifer and well properties, groundwater monitoring,
dewatering and supply for both public and private sectors in India and Singapore. Successfully lead
various projects for the assessment of water use, demand, development scenarios and water
sustainability, and in the design and implementation of well field protection plans and identification of
source vulnerability assessment and source water protection plans. Published his work in various
international and national journals, which includes 5 in international journals and 11 in national
journals, on the topics concerning hydrogeology, well hydraulics, hydro-geochemistry, hydro-
geomorphology and groundwater qualities.
