I'm looking at how people change their travel behaviours under new urban models (15-minute city, LTN, car-free city, superblock model, cycling infrastructure, active travel), and how people interact with their physical environment to model underlying environmental exposures (air quality, noise, physical activity, access to green and blue spaces, traffic accidents/injuries, and heat exposure). All of these factors together influence population health, including illness and even death. I was actively involved in JIBE and GLASST. Now, I contribute to DARe.
