5/1994 – 8/1999
Research Fellow, School of Environmental Sciences, Jawaharlal Nehru University, New Delhi, India. I was selected to work in a Ministry of Rural Development funded project. The main theme of the project was fluoride and related element in groundwater of an arid region (Ajmer District, Rajasthan). This is not an independent work and it involved a team of members including a Research Associate, a Project Director at University and a scientific advisor at Government Ministry. The project progress evaluated yearly on the basis of its achievement by furnishing compiled data, report presentation and further get extended.

Courses developed for Post Graduates
Students seeking a Master degree in Environmental Engineering are broadly educated in all areas of science and natural resources. Course work includes Introduction to Natural Water Resource, Ecology, Geochemistry, Hydrology, Introduction to Water Science, Soil Conservation and Watershed Management, Water Resources Seminar, and one course each in climate, geographic information systems and geology. Students select an additional course in natural resources, soils, irrigation, or aquatic ecology. Prior to the beginning of the first year, students must specialize in one of the five option areas listed below.
This option is designed for students interested in geochemistry of lake, river, stream, or wetland. Students are prepared for careers as research scientists or technicians with public agencies, private consulting firms, universities, and non-profit organizations. Course work includes River and Stream Ecosystem, Biogeochemical Cycles and Geochemistry. Students select one other course from Aquatic geochemistry, Freshwater chemistry, Lake and Reservoir Restoration, Wetlands or estuarine system.
This option trains students in the quantitative aspects of hydrologic sciences and is designed for students considering careers as a professional hydrologist, research scientist, or consultant (among others). Course work includes, Groundwater Geology, and Soil conservation. In addition, students choose one additional course from Surface Water Hydrology, Field Techniques in Hydrogeology, and Water in Geosciences.
This option trains students with a desire to pursue a career examining water quality within lakes, streams, rivers, and groundwater. This option is designed for students considering careers as water quality specialists, research scientists, laboratory and field technicians, environmental chemists, and many more. Course work includes Chemistry of Natural Waters, Water Quality Strategy, and Soils chemistry, Environmental sciences and Water Quality. Students select two more courses in either geomicrobiology, Surface Water Hydrology, Groundwater Geology, Biogeochemical Cycles, Water in Geosciences, Lake and Reservoir Restoration, River and Stream Ecology.
