Welcome to the Smart, Equitable, Resilient Mobility Systems (SERMOS) Lab!

The SERMOS Lab is led by Dr. Xilei Zhao, Assistant Professor in Civil and Coastal Engineering at the University of Florida. We invent and apply computational and data science methods to create smart, equitable, resilient mobility systems. Our interdisciplinary team is made up of transportation engineers, urban planners, computer scientists, and industrial and operations engineers. Our expertise includes:

  • Big data analytics and travel behavior modeling for emerging travel modes (e.g., ridesourcing and micromobility)
  • Modeling and planning evacuation
  • Quantifying resilience for critical infrastructure systems, societal systems, and communities
