Introduction
Hi! I am a second-year Ph.D. student in Intelligent Transportation Systems under the supervision of Professor Raphael Stern at the University of Minnesota (UMN). Specifically, I am working on topics that include machine learning in transportation, Transportation-Cyber-Physical systems (T-CPS), and transportation safety. My research leverages data and computation to apply them to traditional transportation engineering challenges and to understand and design future cities.

Max-pressure signal control has been analytically proven to maximize the network throughput and stabilize queue lengths whenever possible. Since there are many transit lines operating in the metropolis, the max-pressure signal control should be extended to multi-modal transportation systems to achieve more widespread usage. The standard max-pressur...
The explosive popularity of transportation network companies (TNCs) in the last decade has imposed dramatic disruptions on the taxi industry, but not all the impacts are beneficial. For instance, studies have shown taxi capacity utilization rate is lower than 50% in five major U.S. cities. With the availability of taxi data, this study finds the ta...
The explosive growth of transportation network companies (TNCs) in the last decade has posed dramatic disruptions on the taxi industry. This paper investigates how ridesourcing services impacted the taxi industry from both spatial and temporal perspectives in the city of Chicago. With the taxi data from 2014 to 2019 and TNCs data in 2019 from the C...
