Mark Z. Jacobson is Director of the Atmosphere/Energy Program and Professor of Civil and Environmental Engineering at Stanford University. He is also a Senior Fellow of the Woods Institute for the Environment and of the Precourt Institute for Energy. He has been on the faculty at Stanford since 1994. His research involves the development and application of numerical models to understand the effects of energy systems, vehicles and other emission sources on climate and air pollution and the analysis of renewable energy resources. He received the 2005 American Meteorological Society Henry G. Houghton Award, based in part on his discovery that black carbon may be the second-leading cause of global warming after carbon dioxide. He co-authored a 2009 cover article in Scientific American (with Dr Mark DeLucchi) on how to power the world with renewable energy. In 2010 he was appointed to the Energy Efficiency and Renewables Advisory Committee by the US Secretary of Energy. He has taught courses on Atmospheric Pollution and Climate; Weather and Storms; Air Pollution Modeling; and Numerical Weather Prediction. He has published over 110 peer-reviewed journal articles and another textbook: Fundamentals of Atmospheric Modeling (Second Edition, 2005; Cambridge University Press).
