Main research topics:

  1. Social networks, travel behavior and joint decision-making processes
  2. The effect of new transportation technologies on travel behavior and urban form
  3. Travel behavior changes during the COVID-19 Pandemic
  4. Validation methods for discrete choice models

See some highlights of specific projects below. More generally, my research output list is here.

①Social networks, travel behavior and joint decision making processes

As social animals, many of our decisions are made in coordination with members of our social groups. However, the traditional approaches to travel behavior modeling do not take into consideration this very important factor. The purpose of this project is to better understand how we make travel-related decisions in the groups we belong to. To do so, we are working on 1) novel data collection methods to collect data on joint travel behavior and its joint decision-making processes and 2) both qualitative and quantitative methods to better understand and ultimately model these processes.

②The effect of new transportation technologies on travel behavior and urban form

The transportation field is undergoing fast changes in terms of technological development. While these technological innovations promise to solve many of our urban problems, risks exist that the might contribute to exacerbate them if left unchecked. The purpose of this project is to understand the potential effects of these technologies on travel behavior and urban from to guide related policy making.
