Research Areas

Current research projects include:

  • Developing innovative technologies to remediate groundwater contaminated by persistent and toxic fluorochemicals (e.g., PFOS, PFOA)
  • Assessing the effectiveness and sustainability of ion exchange treatment processes for per- and polyfluoroalkyl substances (PFAS)
  • Valorizing waste streams through integrated biochemical-hydrothermal-catalytic conversion processes that produce liquid fuels, valuable industrial chemicals, and fertilizer
  • Advancing heterogeneous catalytic technologies for reduction of toxic oxyanion groundwater contaminants (e.g., nitrate and perchlorate)
  • Developing models that can be integrated into biorefinery systems optimization platforms to reduce production costs and life cycle environmental impacts of algae biofuels
  • Identifying the dominant mechanisms controlling the transformation of organic micropollutants of emerging concern (e.g., pharmaceuticals, flame retardants) in reclaimed wastewater systems
