  • I am currently an Associate Professor at Dynamics and Control lab , Department of Electrical Engineering, IIT Madras. I obtained my PhD in systems and control from University of Twente, The Netherlands and held post doc positions at University of Melbourne and UCLA.
  • My interests lie in the area of modeling and control of complex physical systems. I also have interests in the area of identification and control of (cloud) computing systems and analysis and control of power, traffic, brain and cloud networks.
  • I am also a associated with the Robert Bosch Center for Data Sciences and Artificial Intelligence at IIT Madras.

  • My research interests lie in the area of systems and control theory.
  • In particular I am interested in modeling and control of complex physical systems in the port-Hamiltonian framework.
  • I also have interests in the area of modeling and control of (cloud) computing systems and data analytics for power, cloud and traffic networks.
