Our Focus

My research group focuses on understanding the relationship between organic micropollutants and the environment around them. Specifically, we research how micropollutants impact our biological engineered processes, and how engineered processes can be altered to mitigate the effects of micropollutants in the natural environment. My broader research interest is harnessing wastewater treatment to recover energy, nutrients, and clean water.

Specific Research Interests:

  • Impact of micropollutants on microbial communities
  • Removal of micropollutants from liquid and solid effluents
  • Estrogenic compounds
  • Antibiotic resistance
  • Residuals and biosolids
  • Pyrolysis

Our group is currently researching:

  • Antimicrobials and antimicrobial resistance genes in anaerobic environments
  • Novel applications for the removal of micropollutants from dilute wastewater streams
  • The impact of pyrolysis on the fate of micropollutants in biosolids
  • Pyrolysis for biochar production from biosolids and reduction of estrogenicity
