Mark P. Van Oyen



2853 IOE


Prof. Van Oyen joined IOE in 2005. His current research emphasizes healthcare operations and medical decision making. His interests include predictive methods (machine learning, Kalman filtering, etc.) and the analysis, design, control, optimization, and management of stochastic systems. He co-authored papers that won the 2016 Manufacturing and Service Operations Management (MSOM) Best Paper award, 2016 MSOM Service Science SIG best paper award, 2010 Pierskalla Award, first prize winning papers in the 2016 and 2011 POMS CHOM competitions (with second prizes in 2013 and 2011). His awards with student advisees include 2nd prize in the Dantzig Dissertation Award, first prize in the 2012 MSOM Student Paper Competition (and two other finalist paper in other years) and the 2012 INFORMS “Doing Good with Good OR” first prize. He was the IOE Dept. Faculty of the Year for 2008-9, and the 2003 Researcher of the Year at Loyola University Chicago’s School of Business. He has served as Associate Editor for Management Science, Operations Research, Naval Research Logistics, IIE Transactions, and IIE Trans Healthcare Syst. Engr., Senior Ed. for Flexible Services & Manufacturing, and the Ed. Board of Service Science. He was a faculty member of the Northwestern Univ. Sch. of Engr. (1993-2005) and Loyola Univ. of Chicago’s Sch. of Bus. Admin. (1999-2005). He has received grant funding from the NSF, NIH, NEI, ONR, EPRI, Glaucoma Res. Found., ALCOA, GM, and the VA.
