Timothy J. Strathmann

Professor, Civil and Environmental Engineering

timothy-strathmann-2-300x300 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 treat highly reclacitrant per- and polyfluoroalkyl substances (PFASs), produce bio-renewable energy and chemicals, and recover valuable resources from waste streams.
