I am a Research Scientist at Vanderbilt University - ISIS. I am a senior member of IEEE and hold a MS from the Mechanical Engineering Department at MIT and a PhD in Electrical Engineering from The University of Notre Dame.
My research develops constructive resilient networked control principles for Cyber Physical Systems. The principles I've developed apply to non-linear affine systems, including fixed wing aircraft, quadrotor aircraft, robotic, thermal, semiconductor manufacturing, alternative energy generation, digital signal processing, and suspension systems. I am author or coauthor of over 50 publications, including 14 US patents. I am now working on a groundbreaking result showing these nonlinear affine systems can be expressed through what I term "m-Triangular Systems". The m-Triangular System renders possible a well-posed, distributed, continuous-time, nonlinear control law which can be applied to nonlinear affine systems. This control law creates a strictly-output passive system which can then be integrated into a multirate discrete time networked control architecture. This robust architecture permits a discrete time strictly passive lag compensator to determine the desired output of the strictly-output system. Thus, we can integrate unmanned aircraft into the NextGen system in which the lag compensator is located at the ground-control station. We can now safely control the inertial position of these aircraft despite communication time varying delays and data loss.
