I will be presenting at the 2025 INFORMS Annual Meeting. I kindly invite you to attend my talk! (Please see the start page for more infomation)
In response to demand that has surged in both diversity and intensity, curb space has become an increasingly vital interface between infrastructure and a wide range of transportation users. My research addresses the need for effective curb space management to support emerging mobility options, ensure equitable access, and maintain proximity to key urban activities. Using mathematical frameworks, I develop network and infrastructure models, design operational policies, analyze user behaviors, and create solution algorithms and software tools that together aim to identify socially optimal strategies while supporting user adaptation to evolving curb space systems.
Play Curb Tycoon Jr.! This interactive game (beta) introduces the ideas behind my research on dynamic curb space management in a fun and engaging way.
I propose a foundational work that allows curb space as a shared resource in urban environments, where its utilization is maximized under dynamic usage allocation and pricing schemes.
Dynamic policy
Infrastructure management
Stackelberg game
Bi-level optimization
Benders decomposition
I suggest how spatial heterogeneity and time-varying preferences of decentralized users can be integrated into curb pricing strategies to enhance the utilities of both the curb space operator and the users.
Spatiotemporal pricing
Subsidy program
Mathematical programs with complementarity constraints (MPCC)
Lagrangian relaxation
I design resilient curb space development planning under fluctuating paces of technological development, changing budget availability, and increasing demand uncertainty.
Infrastructure planning
Electrification
Stochastic optimization
Sample average approximation (SAA)
Column generation
I develop a microsimulation model that examines the dynamic interactions among users of multiple curb space usages while jointly responding to curb space operational policies, individual characteristics, and actions of other users.

Behavioral analysis
Illegal behaviors
I dissect the impacts of selfish curb user behaviors on system utility and examine how to remedy them through appropriate regulatory measures.

Equilibrium modelingÂ
I formulate a mixed-integer linear program to extend bicycle networks within a budget, aiming to maximize potential cyclists, minimize route deviations, and increase bicycle mode share on the curb.
