He is also a member of the Scientific Steering Committee of the Urban and Global Environmental Change core project of the International Human Dimensions Programme. Stephen Hammer is the Executive Director of the Energy Smart Cities Initiative, a project of the Joint U.S.-China Collaboration on Clean Energy (JUCCCE), which runs energy and climate policy training and technical assistance programs for local governments around China. Stephen joined JUCCCE in January 2010 after serving as director of the Urban Energy Program at Columbia University's Center for Energy, Marine Transportation and Public Policy. He has authored or co-authored dozens of policy studies and journal articles on urban sustainability planning, urban energy systems, distributed generation technology and the impacts of climate change on local and regional energy networks. In addition to his work at JUCCCE, Stephen is an Adjunct Professor at Columbia University, a member of New York City Mayor Bloomberg's Energy Policy Task Force, a consultant to the State of New York on microgrid and climate change adaptation issues, and a policy advisor on urban energy efficiency to the World Bank. Shagun Mehrotra is Managing Director of Climate and Cities, an international policy advisor facility at Columbia University's Center for Climate Systems Research. As a Columbia University Faculty Fellow, he provides research and policy advice focusing on infrastructure economics and finance, development economics and poverty reduction in slums. He has developed a comprehensive framework for city climate risk assessment that combines hazards, vulnerabilities and agency. Previously, Shagun was on the staff of the World Bank, leading infrastructure reform of state-owned utilities in Africa. Over the last decade, his advice has been sought by national and local governments in East Africa, South-East Asia, China and India, as well as the United Nations' Human Development Report, the Bill and Melinda Gates Foundation, and the Columbia Earth Institute. The President of India recently launched Shagun's co-authored book Bankruptcy to Billions: How the Indian Railways Transformed, with a foreword by the Prime Minister of India.
