I strive to conduct research that helps professionals and policymakers make better decisions when planning, engineering, and designing cities and infrastructure. I was motivated to become a professor and researcher after spending a decade working in California as a transportation and air quality planner, witnessing firsthand the need for strong evidence in decision-making. Linking research and practice is central to my work. To date, I have been PI or co-PI on nearly $4 million in funded research. My work is published in peer-reviewed journals, as well as technical reports and other venues. I often collaborate with colleagues in other disciplines, including civil engineering and psychology, as well as my students.
