Dr. Steve Gabriel is a Professor in the Mechanical Engineering Department at the University of Maryland with additional appointments as Professor, Applied Mathematics, Statistics, and Scientific Computation Program and Affiliate Professor, Institute for Systems Research. He is also the Academic Advisor for the Energy Systems Management and Policy certiificate program.

Dr. Gabriel has extensive experience in both mathematical modeling as well as algorithm design for optimization and equilibrium (i.e., complementarity) problems in a variety of engineering and economic areas such as energy, the environment, transportation, and telecommunications. In addition to his academic background, he has over 25 years experience in industry in mathematical modeling and analysis. He has an M.S. in Operations Research from Stanford University, and an M.A. and Ph.D. in Mathematical Sciences from the Johns Hopkins University. Prior to joining the University of Maryland in 2000, he was a project manager for energy modeling at ICF Consulting, a postdoctoral researcher at Argonne National Laboratory, an Operations Research Analyst at Arthur D. Little, Inc., a Systems Analyst with Technology Systems, and a Market Analyst for a kerosene heater company.

Professor Gabriel has over 60 publications in refereed journals, conference proceedings, and technical reports. He has been an expert panelist for the DOE (Energy Information Administration and National Technology Laboratory) in providing guidance on building an international natural gas model as well as evaluation of their fossil energy programs. Also, he has been a guest researcher at the Energy Research Center of the Netherlands in Amsterdam assisting with building certain aspects of their European natural gas market model. Lastly, Professor Gabriel works extensively with both Masters and Ph.D. students in modeling and algorithmic design for infrastructure problems. Dr. Gabriel is a member of the Institute for Operations Research and the Management Sciences (INFORMS), Mathematical Programming Society (MPS), and a Senior member of IEEE. In addition, he was as Associate Editor for energy at Operations Research and is currently the Area Editor for energy for Networks and Spatial Economics and an Associate Editor for Energy Economics.
