Jacobson is a professor of civil and environmental engineering and director of the Atmosphere and Energy Program at Stanford University. He is also a senior fellow at the Woods Institute for the Environment and the Precourt Institute for Energy, both at Stanford. The main goal of his research is to better understand severe atmospheric problems such as air pollution and global warming, and to develop and analyze large-scale renewable energy solutions to them. He has developed a number of computer models for simulating air pollution and its effects on climate. In 2009, Jacobson and Delucchi co-authored a seminal report on how to power the world on renewable energy alone.
