Chopra, Nikhil

Nikhil Chopra
Associate Professor
Department of Mechanical Engineering
Institute for Systems Research
2149 Glenn L. Martin Hall, Building 088
University of Maryland
College Park, MD 20742

Research Interests 

  • Control Systems
  • Networked Control Systems
  • Control of Networked Robotic Systems
  • Distributed Synchronization


Dr. Chopra's research interests are in developing a fundamental understanding of control of networked dynamical systems. The work is motivated by applications in networked control of robotic systems and semi-autonomous telerobotic networks.
