91����Ƶ

Biography

During my 26-year career at IBM, I developed and applied operations research methods to complex decision problems in supply chain management, and held job titles that included Master Inventor and Senior Engineer. Since leaving IBM in 2010, it has been my pleasure to teach courses at 91����Ƶ in operations research, operations and supply chain management, and a third course that presently involves students developing patentable inventions. My research has focused on extending operations research methods to address problems in supply chain management, planning, and scheduling. I am among the world’s experts on methods for boarding passengers onto airplanes.

I was the inaugural recipient of the David D. Reh School of Business Faculty Teaching Excellence Award in honor of Dr. Robert John McGill and Dr. Nye Smith, and later received the Reh School’s Faculty Research Excellence Award. The world’s leading professional society for operations research and analytics professionals, INFORMS, honored me with the Franz Edelman Finalist Award for Achievement in Advanced Analytics, Operations Research, and Management Science, the Daniel H. Wagner Prize for Excellence in Operations Research Practice, and elected me a Fellow “for exceptional practice of operations research, extensive service to INFORMS, and outstanding research in planning, scheduling, and supply chain management.” The National Academy of Inventors also elected me as a Fellow.
