Title and Credentials:
Assistant Professor of Chemical Engineering and (by courtesy) Civil & Environmental Engineering
William Tarpeh is an assistant professor of chemical engineering at Stanford. The Tarpeh Lab develops and evaluates novel approaches to resource recovery from “waste” waters at several synergistic scales: molecular mechanisms of chemical transport and transformation; novel unit processes that increase resource efficiency; and systems-level assessments that identify optimization opportunities. Tarpeh focuses on four major aspects of resource recovery: designing adsorbents for selective recovery of nutrients; designing electrochemical recovery processes; tracking contaminant fate, including organic compounds and pathogens; and designing resource recovery in resource-constrained communities. Will aims to selectively extract fertilizers, disinfectants, and commodity chemicals from wastewater, urine, and other waste streams to augment revenues from excreta collection and increase access to sanitation. He has worked on water and sanitation projects in Mexico, Kenya, Senegal, South Africa, Ethiopia, Peru, and Brazil. Will teaches introductory chemical engineering, plant design, and mentors students to combine engineering fundamentals with community-based assessment and technology development.
