Research

Convergence of dramatic increase in the available data and processing power, enabled by ubiquitous sensing and computing capabilities is rapidly changing engineered systems. Cyber-Physical Systems (CPS) refers to such systems with tightly integrated computational, control and physical capabilities, like transportation networks, smart cities, autonomous vehicles, sensor networks, power grids and healthcare systems. However, designing and implementing CPS involve an array of complex and challenging tasks: learning and making inference from data, designing scalable optimization and control methods, and developing decentralized and adaptive decision making algorithms.

My research aims to address these challenging questions in the context of cyber-physical systems, while contributing to the fields such as statistical learning, control theory and game theory. I am especially interested in many applications in the areas of multi-agent systems, intelligent transportation systems and renewable energy systems.

Some specific topics are:

Statistical Learning and Optimization

Theory: Sequential Learning, Online Convex Optimization, Multi-Armed Bandits, Reinforcement Learning, Recurrent Neural Networks.

Applications: I am interested in developing decentralized learning algorithms for multi-agent systems, motivated by the problems in robotics and UAVs. I am also working on developing data-driven learning and optimization algorithms for intelligent transportation systems. For example, how do we exploit the historical data and high-resolution real time data to predict future traffic flow and signal timings? I use machine learning techniques to develop scalable learning and prediction algorithms in this context. These algorithms can be used to develop traffic control and routing protocols in transportation networks, to optimize the throughput and reduce queues. I am also interested in using tools from learning theory to model consumer behavior and preferences, especially in the context of energy systems and online markets.

Control Theory:

Theory: Markov Decision Processes, Approximate Dynamic Programming, Decentralized Control, Optimal Control.

Applications: How do we systematically design a scalable distributed control architecture that will give provable stability, robustness and high performance in the presence of uncertainty and stochasticity? This is the fundamental question that I am interested in. In particular, I am working on developing decentralized control algorithms for multi-agent systems, motivated by the problems in robotics and UAVs. I am also interested in control problems in the context of intelligent transportation systems. Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I) and Vehicle-to-Cloud (V2C) communication capabilities have the potential to dramatically change the transportation systems operation in terms of improving road safety, alleviating traffic congestion and reducing fuel consumption. However, this requires innovative (decentralized) control design coupled with scalable learning and prediction algorithms. Some of my recent works are in this context.

Game Theory:

Theory: Stochastic Games, Mechanism Design, Learning in Games

Applications: My recent interest is in sharing economy models. In my past works, I have analyzed sharing economy models in the context of electricity networks. I plan to continue my work on sharing economy and extend it to other important application areas. Mechanism design for renewable energy systems, especially for demand response, is another area that I am interested in.
