Areas of Interest

Dr. Bayraksan’s research interests are in stochastic optimization, particularly Monte Carlo sampling-based and data-driven distributionally robust methods for stochastic programming with applications in water resources management. She is the recipient of 2016 INFORMS ENRE Best Publication Award in Environment and Sustainability, 2016 Lumley Research Award (OSU), 2012 NSF CAREER award, 2012 Five Star Faculty Award (UA), and the 2008 INFORMS best case study award. She is currently serving as the Vice Chair of Optimization under Uncertainty in INFORMS Optimization Society and on the editorial board of IISE Transactions. Previously, she served as an elected member (2010-2016) and treasurer (2013-2016) of the Committee on Stochastic Programming (COSP) and president of the INFORMS Forum on Women in Operations Research and Management Science (WORMS).
