Timothy J. Strathmann

Interim Associate Department Head and Professor, Civil and Environmental Engineering

Timothy StrathmannProfessor Strathmann’s research group applies modern chemical research tools and techniques to develop more sustainable technologies for environmental and energy applications. The group is currently developing technologies that employ innovative catalytic, hydrothermal, and photochemical processes to purify water, produce bio-renewable energy and chemicals, and recover valuable resources from waste streams.

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
