Senior Research Analyst

Jim Sullivan is a Senior Research Analyst at the UVM Transportation Research Center. Prior to his research career at UVM, he worked in the private sector as a consulting engineer for 15 years. He holds a professional engineering license and is pursuing a Ph.D.

Jim leads projects in the research areas of land-use and transportation modeling, transportation energy and system efficiency, and winter maintenance. His modeling research includes applications of critical-infrastructure modeling platforms for testing of various measures of network performance under scenarios of disruption. Applications of risk-based methods for assessing critical infrastructure have included passenger-vehicle transport, freight transport, delivery of emergency services, and provision of snow and ice control, all under disruptive scenarios created by severe weather.

Additionally, Jim currently maintains and operates the statewide travel-demand model for Vermont under contract to the Vermont Agency of Transportation, along with a variety of research projects related to transportation demand, behavior, and energy use. Although Jim works on numerous critical research themes, the aspect he values most about his position with the TRC is the opportunity to work alongside various accomplished faculty members and colleagues.
