Research Interests

Nutrient recovery through urine separation, Life Cycle Assessment, Water Systems, Circular Economy

Stephen is working on assessing a new form of recycling: Pee-cycling. Instead of adding nutrient heavy urine to the wastewater treatment system and intensively treating the nitrogen and phosphorus as a waste, the project looks to create fertilizer with it instead. He is developing life cycle models to analyze the environmental trade-offs of this approach with the conventional wastewater treatment system.
