I am a Distinguished Research Staff Member and the Area Head of Stochastic Processes, Optimization and Control within the Mathematical Sciences Department at the IBM Thomas J. Watson Research Center. I also serve as Director of the Center for Optimization under Uncertainty Research across IBM Research. I received a Ph.D. degree from the University of Washington (Seattle, WA). I have been an adjunct faculty member in the School of Engineering and Applied Science at Columbia University (New York, NY), and a Member of the Technical Staff at Bell Telephone Laboratories (Murray Hill, NJ); I am currently an adjunct faculty member in the School of Business at Manhattanville College (Purchase, NY). I have also held visiting positions at various academic institutions.
My research interests broadly concern mathematical foundations of the analysis, modeling and optimization of the design and control of complex systems under uncertainty, including stochastic processes, probability theory, stochastic optimization and control, mathematical statistics, queueing theory, algorithms, and stochastic resource allocation/scheduling, as well as their extensive applications in the areas of decision making under uncertainty, business analytics and optimization, data analytics, financial analytics, smarter planet technologies, health analytics, smart energy/grid technologies, smarter workforce/salesforce, social media analytics, data-centric and cloud computing, computer systems, communication networks and mobile devices, revenue and risk management, and manufacturing and service operations management.
I am an elected Fellow of ACM, IEEE and INFORMS, and the author of more than 250 technical papers and more than 45 issued/filed patents and disclosures. My work has been recognized through The Daniel H. Wagner Prize (INFORMS), The Gold Stevie® Award (Sales Automation Solution), 8 best paper awards, 15 keynote/plenary presentations, 17 major IBM technical awards, and 27 IBM invention awards. I am a member of AMS, Bernoulli Society for Mathematical Statistics and Probability, IMS, IFIP WG 7.3 (elected), and SIAM, recently being elected to serve as Chair of IFIP WG 7.3 and as Chair of the Computer Performance Foundation. I currently serve on the editorial boards of ACM Transactions on Modeling and Performance Evaluation of Computing Systems, Performance Evaluation and Stochastic Models, and have also chaired/organized several international conferences in stochastic processes, applied probability, stochastic optimization/control and related applications.
