Lead Researcher (Tom Holub)

Living car-free in the Bay Area since 1990, I have watched as utility cycling has gone from marginalized to mainstream. It has been fascinating to see the changes in culture and infrastructure, and I have long been curious about how it happened, and what the effects have been on cities. I am interested in investigating the causal links, and bringing a quantitative and analytic approach to the research.
