Harriet is the Director of NUMO, the New Urban Mobility alliance, hosted by WRI Ross Center for Sustainable Cities. NUMO is a new collaborative effort that aims to guide policymakers, the private sector and people toward a shared vision of cities and urban mobility.The pace of technology-driven disruption in transportation is not only changing how people get around but changing cities themselves. Governments, companies, non-profits and residents are increasingly asking how to incorporate ride-hailing, dockless bikes and scooters, and even autonomous vehicles into their communities in the best way. NUMO aims to help answer these questions through collaboration with alliance members around research priorities, innovative pilot projects, public engagement and policy development in cities around the world. NUMO is an outgrowth of the Shared Mobility Principles for Livable Cities, which more than 170 companies and governments have signed on to as a guiding vision for more sustainable, inclusive, prosperous and resilient cities.Harriet has been deeply engaged on planning, smart mobility, disaster resilience, housing and community development issues for the past 2 decades. She has been working with organizations around the country to help states and localities prepare for a range of future challenges, including smart mobility; climate change; disaster recovery and resilience; housing affordability; and community development. She served in the Obama Administration as Principal Deputy Assistant Secretary of the Office of Community Planning and Development at the U.S Department of Housing and Urban Development. She initiated the first ever $1 billion National Disaster Resilience Competition. Her work encompassed helping states, regions, cities, counties and towns across the country build a strong foundation for resilience in the face of a changing climate, and for a diverse and prosperous economy based on enhancing community quality of place, economic opportunity, fiscal stability, transportation choice, and affordability. She was the Director of the District of Columbia Office of Planning under the past 2 Mayors, where she worked to make DC a walkable, bikeable, eminently livable, globally competitive and thriving city.She studied Engineering and Public Policy at Washington University.
