Dr. Manoj Kumar is an environmentalist specializing in hydrogeochemistry. Dr. Kumar obtained his Ph.D. in Environmental Sciences from Jawaharlal Nehru University, New Delhi, in 2017. Currently as an Assistant Professor at IISER Mohali, Dr. Kumar brings a diverse academic background, having previously served at the Central University of Haryana (2016–2023), briefly at IISER Thiruvananthapuram, and as a Lecturer at IISER Mohali during 2023–2024. Dr. Kumar’s research primarily addresses groundwater contamination, with a special emphasis on geogenic contaminants such as arsenic and fluoride, affecting drinking water supplies in various regions worldwide. He has successfully supervised and co-supervised over 80 M.Sc. dissertations. In recognition of his contributions, Dr. Kumar was awarded the prestigious Crawford Fund Fellowship in 2013.

The research group led by Dr. Kumar focuses on hydrogeochemistry and environmental geosciences, with an emphasis on understanding groundwater quality, water–rock interactions, and contaminant transport in diverse geological settings. The group integrates field investigations, laboratory analyses, and geochemical modeling to assess the impact of natural processes and anthropogenic activities on water resources. Ongoing projects explore issues such as groundwater contamination, trace element mobility, and sustainable water management in vulnerable regions.
