Our Focus

My research group focuses on understanding the dynamic relationship between organic micropollutants and the built and natural environment. I am interested in both sides of this relationship, i.e. how are micropollutants impacting our biological engineered processes, and how can engineered processes be augmented to mitigate the effects of micropollutants in the natural environment? My broader research interest lies in securing the sustainability of wastewater treatment, which relies upon the ability of wastewater treatment to recover energy, nutrients, and clean water. Under this paradigm, my interests are in removing micropollutants from both wastewater liquid effluents and residuals and biosolids. In particular, I research the role that micropollutants play in the spread of antimicrobial resistance genes, and how advanced wastewater treatment processes can remove micropollutants from biosolids while yielding a rich soil amendment for recycle through land application.

Our group is currently researching:
*Antimicrobials and antimicrobial resistance genes in anaerobic environments
*Novel applications for the removal of micropollutants from anaerobic wastewater

*The impact of pyrolysis on the fate of micropollutants in biosolids
*Pyrolysis for sustainable treatment of biosolids and reduction of estrogenicity
