Fall Colloquium Series: Dr. Yujie Hu
Bio: I am a geographer with research and teaching interests in urban transportation, human mobility, and accessibility. My current research focuses on three main areas: 1) relationships between people’s mobility within cities—including commuting, healthcare-seeking, and crime—and the urban built environment, 2) accessibility to opportunities, such as jobs, healthcare, food, and transportation infrastructure, and how it is affected by natural hazards, and, 3) network flow analysis and optimization of travel patterns related to commuting, bike sharing, healthcare, and food delivery.
My main research approach is the development and application of GIS, network analysis, and machine learning/AI techniques to reveal patterns of individual and group behaviors from big geospatial data associated with point patterns (traffic crashes, crime incidents) and networks (movement trajectory such as taxi cab GPS trajectory, smart card transaction data, and origin-destination flow such as commuting, bike sharing usage, and inpatient discharge). The goal is to convert data into knowledge to inform and evaluate place-based policies focused on transportation, land use, public health, and community safety.
