Specific research interests
  • Qualitative and quantitative estimation of macro and micro plastics in the marine environment(delta regions, marine waters, beaches), surface waters (rivers, lakes and ponds), soils and air

  • Understanding the fate of toxic nanoparticles as function of prevailing hydrogeochemistry of the riverine environment (nanoparticles: nanoplastics, nanopesticides, metal oxides, etc)
    • Stability, aggregation kinetics
    • Deposition / re-entrainment
    • Transport
    • Degradation

  • Factors contributing to accumulation of contaminants (metals, dyes, persistent organic pollutants, PAHs, PCBs) in the riverbed and sediments

  • Impact of  pollution on groundwater hydrogeochemistry 

  • Finding the human exposure pathways to contaminants (metals, plastics, pesticides etc) through food, water and air

  • Synthesis, characterization and applications of eco-friendly nanocomposites for environmental applications​
    • Removal of metals, metal nanoparticles, pesticides, dyes from wastewater
    • Remediation of metals in soils
    • Reduction of metal accumulation in plants grown in contaminated soils
    • Real-time detection of contaminants (pesticides, plastics, metals) in the environment using portable sensors
