General information

Professor Ghoshal's expertise is in the area of geoenvironmental engineering. His research includes the remediation of contaminated soil and groundwater, and the fate and transport of organic compounds, pathogens and engineered nanomaterials  in the water and soil environments. Research activities include laboratory studies and mathematical modelling of physiochemical and biological processes.


Research interests

  • Experimental evaluation and mathematical modelling of fate and transport processes of organic and colloidal pollutants in natural environments and in treatment systems.
  • Evaluation, assessment and development of soil and groundwater remediation technologies for sites contaminated with chlorinated solvents, petroleum oils, coal tars, pesticides and complex chemical mixtures.
  • Pathogen transport and survivability in porous media.
  • Green house gas mitigation through carbon dioxide disposal in deep saline aquifers and through mineral sequestration.

Selected current research projects

  • Characterization and fate of engineered nanoparticles in wastewater
  • Use of iron nanoparticles for in situ remediation of chlorinated solvent sites
  • Bioremediation of petroleum petroleum hydrocarbons Arctic and sub-Arctic (cold) regions
  • Effects of freeze-thaw on transport and survivability of pathogens in porous media
  • Sequestering carbon dioxide by Accelerated Curing of Concrete
  • Characterization of petroleum contamination in soils using Computed Tomography (CT) X-ray scanning
