Joseph Ryan serves as Program Officer in the Environment Program. In this position he coordinates all the Foundation’s international air quality and transportation projects. This work follows four broad themes: (1) introducing ultra-clean fuels in developing nations, (2) dramatically reducing emissions from cars and trucks through regulation, (3) working with government and the private sector to promote cleaner technologies for heavy-duty vehicles, and (4) promoting economically viable public transportation options. Key areas include Bus Rapid Transit (BRT), traffic control measures like congestion charging and improved pedestrian and bicycle access. These areas of work support the Program's overall mission to improve the lives of residents in the developing world’s largest cities, focusing particularly on megacities in Mexico, Brazil, and China. Joe has lived and worked in Latin America for the past fifteen years, including five full-time in Brazil working with the Hewlett Foundation. A former Fulbright-Hays doctoral fellow, Joe has a Ph.D. in history from the University of California, Los Angeles.
