Biography: 

Professor Ghoshal's expertise is in the area of environmental engineering. He conducts research on the remediation of contaminated soil and groundwater, and on soil and water quality. His current research in on the environmental fate, transport and reactivity of engineered nanomaterials and nanopesticides, and on adapting bioremediation practices for sub-arctic regions. The research involves both laboratory studies and mathematical modelling of physiochemical and biological processes.
