Dr. Alok Kumar

M.Sc., M.Phil., Ph.D. (Environmental Sciences)

  • Biogeochemistry
  • Hydrogeochemistry
  • Biomarkers

B.Sc.- 2002-2005; D.A.V. College, Panjab University, Chandigarh

M.Sc.- 2005-2007; School of Environmental Sciences, Jawaharlal Nehru University, New Delhi

M.Phil.- 2007-2009; School of Environmental Sciences, Jawaharlal Nehru University, New Delhi

Ph.D.- 2009-2015; School of Environmental Sciences, Jawaharlal Nehru University, New Delhi

My teaching interests include Environmental Geosciences, Coastal and Marine Environment, Instrumentation for Environmental Monitoring and Analysis, and Ecology and Ecosystems etc.

My research focuses on the biogeochemistry of aquatic ecosystems (both freshwater as well as saline). My research investigates the natural and anthropogenic controls on elemental cycles at regional and global scales. I started my investigations with Hydrogeochemistry of the Gangetic plains and then expanded to investigate the soils and sediments in the coastal and floodplains sediments.

My doctoral research focused on the biogeochemistry of Sundarban mangrove ecosystem.

My present research focuses on the biogeochemistry of playas in the arid and semi-arid environment of Rajasthan targeting lacustrine environment at an ecosystem level.

I am also interested in the global carbon cycle and how does it respond to natural and human-driven changes. I also look into the pollution aspects of wetlands via investigating the elemental cycles.
