  • Urban Transformation

Julia leads a new global program working with cities to reduce transportation emissions by changing how much people drive, investing in equitable mobility options, and  building affordable and accessible new housing. The team’s data-informed research helps cities target key policies for impact, develop and implement transformational projects, and build stakeholder support.


Prior to working at RMI, Julia served as the executive officer of economic development for the Los Angeles Mayor’s Office, where she oversaw $150 million of direct financial assistance to small businesses during the COVID-19 pandemic, drove sustainability policy at the Port of Los Angeles, and led mobility innovation programs across LA’s transportation departments. Julia previously worked as director of urban development at the infrastructure and technology company Siemens, consulting on sustainability initiatives for 35 cities across Asia, Europe, Latin America, and North America. She is also founder and board member of the public-private transportation innovation hub Urban Movement Labs, and an educator at USC’s Sol Price School of Public Policy. Her work has been featured in publications including Fast Company, Washington Post, City Lab, Vox, Bloomberg, Governing Magazine, Quartz, Tech Crunch, and Curbed.
