George Nemhauser is an A. Russell Chandler III Chair and Institute Professor Emeritus in the H. Milton Stewart School of Industrial and Systems Engineering.

Dr. Nemhauser received a Ph.D. in operations research from Northwestern University in 1961, and joined the faculty of Johns Hopkins University where he remained until 1969. In 1970, he joined Cornell University as a professor in operations research and industrial engineering and served as school director from 1977 to 1983. He has held visiting faculty positions at the University of Leeds, U.K. (1963-64), the Center for Operations Research and Econometrics (CORE), University of Louvain, Belgium (1969-70, 1975-77, 1983-84) and the University of Melbourne, Australia (1995). He was the Research Director at CORE from 1975-77. He  has served the Operations Research Society of America (ORSA) as council member, president, and editor of Operations Research, and was chair of the Mathematical Programming Society. He was the founding editor of Operations Research Letters, and founding co-editor of Handbooks of Operations Research and Management Science.

Dr. Nemhauser has served various governmental agencies, including the NSF, the National Institute of Standards and Technology (NIST), and the National Research Council (NRC). He was a member of the NRC's Board of Mathematical Sciences. His honors and awards include membership in the National Academy of Engineering, the Kimball Medal, the Lanchester Prize (twice awarded), Morse lecturer of INFORMS, the Khachiyan prize of INFORMS for lifetime achievements in optimization and, most recently, the John von Neumann theory prize of INFORMS. His current research interests are in solving large-scale mixed-integer programming problems. He is actively working on several applications, including maritime inventory routing. He is a partner in the Sports Scheduling Group which schedules major league baseball and many university athletic conferences.
