Biography
Tierra S. Bills is an Assistant Professor of Public Policy and Civil and Environmental Engineering at the University of California, Los Angeles. She specializes in the measurement of transportation planning and system outcomes, and travel demand modeling, with a special emphasis on transportation equity. Dr. Bills brings a unique and innovative perspective to the challenge of transportation inequity, aimed at impacting transportation science, practice, and quality of life for disadvantaged communities.

Dr. Bills has extensive training in travel demand modeling and is engaged in ongoing work on representation of transport disadvantaged groups in household travel surveys, which are traditionally used to estimate and validate travel demand models. This is the first step to developing travel models capable of reflecting the preferences and behaviors of disadvantaged travelers and fine-grain transportation equity outcomes.
Dr. Bills has a strong record of advocacy for transportation equity and representation in STEM fields, including providing testimony for the a U.S. House of Representatives’ subcommittee hearing (see: https://science.house.gov/hearings/field-hearing-smart-mobility-its-a-community-issue), membership on the Equity in Transportation Committee of the Transportation Research Board, and co-developing an entry on her research in the ColorMePhD coloring book series (see: https://ce.berkeley.edu/news/2511).
