Biography

I received a B.Tech. in Electrical Engineering from the Indian Institute of Technology, (IIT) Madras, India in 1985. I was at the IIT, Madras from 1980-1985. I have an M.S. and a Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University in Pittsburgh, PA. I was at Carnegie Mellon between 1985 and 1990. I then moved to Harvard University, where I was a Post-Doctoral Fellow in Decision and Control at what was then the Division of Applied Sciences. After a two-year stint at Harvard, I came to the University of Illinois at Urbana-Champaign, where I am an Associate Professor with the Industrial and Enterprise Systems Engineering Department. I hold research appointments at the Coordinated Science Laboratory (CSL) and the Information Trust Institute (ITI). I am also an affiliate of the Electrical and Computer Engineering Department.

Teaching Statement

At the undergraduate level I have taught courses in the controls curriculum (GE320: Introductory Control Systems; GE420: Digital Control of Dynamic Systems; GE423: Introduction to Mechatronics; GE424: State Space Design Methods in Control) in the General Engineering program. I have advised several projects in the industry-sponsored Senior Engineering Project (GE494: Senior Engineering Project I; GE495: Senior Engineering Project II) in the General Engineering curriculum. At the graduate-level I have taught advanced topic courses in the controls and the Industrial Engineering curriculum in the College (AE555: Multivariable Control Design; GE525: Discrete Event Systems; IE511: Integer Programming). I have been involved in the Master of Science in Financial Engineering Program since May 2006, when it was first conceived. This Cross-College Program that now involves several faculty from the Colleges of Engineering and Business. I teach IE523: Financial Computing in this program.  After three years of existence, this program was ranked in the top 20 Financial Engineering programs, by the QuantNet (https://www.quantnet.com/mfe-programs-rankings/).

Research Statement

My current research is on the Analysis, Control and Performance Evaluation of a broad class of systems known to the literature as Discrete-Event/Discrete-State (DEDS) Systems. Examples of DEDS systems include: air-traffic control systems; automated manufacturing systems; computer networks; integrated command, control, communication and information (C3 I) systems; operations-management of multi-component organizations with event-driven dynamics like shipyards, airports, hospitals, etc.

I use the theories of Computation, Coding, Machine Learning, Approximate Algorithms, Online Algorithms and Information Theory to synthesize near-optimal supervisory policies for various problems involving DEDS Systems.

Research Interests

  • Product Development and Manufacturing Automation
  • Coding and Information Theory
  • Petri net Theory
  • Modeling, Analysis, Performance Evaluation and Control of Discrete-Event/Discrete-State (DEDS) Systems
