Research Interests:

  • Physical-Chemical Processes
  • Soil and Groundwater Remediation
  • Environmental Nanotechnology
  • Photocatalysis
  • Water and Wastewater Treatment  

Areas of Specialization

  • Developing novel stabilized nanoparticles for in situ degradation of organic pollutants and immobilization of metals, metalloids and radionuclides in soil and water.
  • Developing adsorptive photocatalysts for adsorption and destruction of persistent organic pollutants such as per- and polyfluoroalkyl substances (PFAS) in contaminated waters and soil.
  • Understanding transformation and environmental fate of spilled oil in seawater and coastal sediment and estuaries and developing cost-effective technologies to control pollution of coastal ecosystems and the nearshore environment.
