Abstract: The increasing frequency of extreme weather events has led to rising network-level failures in transportation systems, such as the 2011 Chicago Blizzard, which trapped hundreds of vehicles due to the propagation of weather-induced congestion. Dr. Huiying ("Fizzy") Fan's research explores how transportation systems respond to climate impacts at a network level, with the goal of developing cyber-physical systems that model network dynamics and support resilience and decarbonization. This talk will focus on resilience, integrating network modeling, high-performance computing, and multi-scale analysis to examine transportation resilience at three levels: cumulative exposure at the individual trip level, cascading failure at the network level, and tipping points at the multi-temporal level. Dr. Fan will also introduce her ongoing efforts in developing cyber-physical infrastructure for resilient and healthy navigation, incorporating weather-informed sensing, HPC-driven simulation, and AI-powered decision support through six core modules: conceptualization, sensing, simulation, prediction, mitigation, and decision support. Looking ahead, her work aims to equip travelers and agencies with theoretical frameworks and computational tools to navigate uncertainties and make informed decisions.

Bio: Dr. Huiying ("Fizzy") Fan is a Research Engineer II at the Georgia Institute of Technology, an ICICLE Fellow at the NSF AI Institute ICICLE, and a Postdoctoral Researcher at IC-FOODS. She earned her Ph.D. in Transportation Engineering from Georgia Tech, a Master's from Duke University, and a BSc from the Hong Kong University of Science and Technology. Her research lies at the intersection of transportation engineering, climate resilience, and data and network science. Dr. Fan examines the complexities of spatiotemporal transportation resilience, focusing on network-level dynamics such as trip-level risk accumulation, cascading failures, and tipping points that could lead to system-wide disruptions. Beyond theoretical contributions, she emphasizes practical applications by developing simulation software tools like SidewalkSim and TransitSim. Outside of research, Dr. Fan has held leadership roles in the Women's Transportation Seminar's Student Chapter and the Community and Ethics Committee at Georgia Tech. She has also contributed to education as a co-instructor and instructor of record for three courses, integrating her interdisciplinary research background into the classroom to foster an inclusive and dynamic learning environment.
