I am a professor of Operations Research at the Tepper School of Business and a professor (by courtesy) at the Department of Computer Science at Carnegie Mellon University.
My research focuses on models, methods and applications of discrete optimization. My research interests are in algorithms for combinatorial optimization, and their applications in the intersection of business and technology. My current research focuses on applications in network design, bioinformatics, supply chain logisitics, mechanism design, and social and information networks.
I am interested in networks and their effects in business, a subject on which I designed and introduced a new MBA class. I am also interested in customer-centric marketing and how to accomplish this using optimization methods on large data sets, on which I co-developed another new MBA class. I also study and teach courses related to business analytics and data mining.
I have a continuing interest in online markets and platforms. I organized a workshop on hurdles to eBusiness in October 2007 from which you can see videos of speakers from eBay , Google and Yahoo. You can also see how accurate I was in predicting the growth of the Android platform in this faculty commentary from November 2007 that resulted from my participation in NPR's Onpoint program on this topic.
My work has been supported by an NSF Career Award, and grants from Google, the NSF and the ONR.
Between the Fall of 2012 until the summer of 2015, I have been the Chair of the Future Educational Delivery Committee that designed and deployed the online hybrid MBA program, the new blended format of the Tepper MBA.
