My research is centered around environmental outcomes and sustainable transportation with an emphasis on the policy implications of individual decision-making and social processes. As a postdoctoral researcher I study emerging on-demand and shared transportation services. These Innovative new services have the potential to significantly alter transportation accessibility and travel patterns; and may reduce or induce greenhouse gas emissions. My doctoral research  investigates the role of social networks and social influence in travel behavior. Social networks may be incorporated into programs aimed at increasing the use of sustainable transportation modes through processes such as information sharing, and the establishment of social norms. See the Social Networks and Travel Behavior project page for more details.
