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.
