Daniel Molzahn joined the faculty of the School of Electrical and Computer Engineering at Georgia Tech in Spring 2019. Prior to this position, Dr. Molzahn was a computational engineer at Argonne National Laboratory in the Center for Energy, Environmental, and Economic Systems Analysis (CEEESA), where he currently holds an affiliate position. He was a Dow Postdoctoral Fellow in Sustainability in the Electrical Engineering and Computer Science Department at the University of Michigan. He received the B.S., M.S., and Ph.D. degrees in Electrical Engineering and the Master’s of Public Affairs degree from the University of Wisconsin-Madison, where he was a National Science Foundation Graduate Research Fellow. In his spare time, Dr. Molzahn enjoys hiking, waterskiing, and climbing. Also, as a shareholder of the world's greatest sporting franchise, he keeps an eye on his investment by watching and attending football games of the 13-time-champion Green Bay Packers football team.

Research interests: 
  • Developing optimization and control algorithms in order to improve the environmental sustainability, economic efficiency, and reliability of electric power systems
  • Addressing non-linearities resulting from the power flow equations
  • Developing mathematically rigorous techniques for incorporating uncertainties related to renewable generation and varying load demands


  • Dow Postdoctoral Fellowship in Sustainability (University of Michigan)
  • National Science Foundation Graduate Research Fellowship (University of Wisconsin—Madison)

Positions held in professional organizations:

  • Vice-chair of the technical program committee for the 21st Power Systems Computation Conference (PSCC 2020)
  • Guest associate editor for a special issue on distributed control and optimization in IEEE Transactions on Smart Grid


  • "High Quality Paper" Award (IEEE PowerTech Manchester 2017)
  • "Best Presentation in Session" Award (American Control Conference 2016)
  • 2014 Harold A. Peterson Best Dissertation Award, Second Place (University of Wisconsin—Madison)
  • Grainger Power Engineering Award (2010, 2008)
