Michael Craig is currently a second-year PhD student in the Engineering and Public Policy Department at Carnegie Mellon University. Before his PhD. he completed an M.S. in Technology and Policy at M.I.T. and, before that, worked in Washington D.C. as the Energy Analyst for Oceana, where he focused on offshore drilling and wind issues. He received his B.A. in Environmental Studies from Washington University in St. Louis. Michael is broadly interested in energy and the environment. His current research focuses on regulations on emissions of carbon dioxide, a greenhouse gas, from the electric power sector. For this research, he uses a power system optimization model that he uses to assess the effects of different policy designs. In his Masters, he worked on a time-differentiated emissions pricing scheme that may reduce pollutants during especially harmful periods, e.g. NOx emissions on high ozone days.
