Sarat Puthenpura is Executive Director of  Service Quality Management Research, responsible for innovating new capabilities to manage end-to-end service quality, using cutting edge analytics and software technologies.  He joined AT&T Bell Labs in 1986 and has worked in a number of areas in telecommunication, predominantly in network planning and optimization spanning both wireless and wireline networks -  in particular applications of mathematical programming techniques to solve complex problems in these areas.  In addition to R&D activities, he has hands on experience in planning, implementing, and operating AT&T’s joint venture GSM network in India (currently Idea Cellular) from 1995 to 1998. Most recently, he has been leading the creation of an integrated network capacity planning and forecasting platform called NOVA (Network Optimization, Visualization and Analysis), which is extensively used for planning AT&T’s UMTS and LTE Radio Access Networks. He is also a subject matter expert in the planning, deployment, and operational aspects of small cells.

Sarat received B.Tech in Electrical Engineering from IIT Madras and Ph.D. in Electrical Engineering from McMaster University, Canada. In addition to several research papers, he has been the author of a graduate level textbook in mathematical programming ("Linear Optimization and Extensions - Theory and Algorithms", Prentice-Hall, 1993).  He has taught in the Department of Electrical Engineering, Industrial Engineering, and well as in the Graduate School of Management, Rutgers University. He is a Senior Member of IEEE and serves on the editorial board of the IEEE/ACM Transactions on Networking.  He is also a NYU WIRELESS Industrial Affiliate board member.

 Current research interests:

  1. End to end service quality management  of VoLTE and video over wireless.
  2. Service quality management of  cloud services.
  3. Service quality management under virtualized network infrastructure.
  4. Application of Big Data in service quality management.
