Piyush Grover

I am a principal research scientist in the mechatronics group at Mitsubishi Electric Research Labs (www.merl.com), in Cambridge, Massachusetts, USA. I obtained a Ph.D. in Engineering Mechanics in 2010 from Virginia Tech, under the supervision of Shane Ross. Most of my work is at the intersection of nonlinear dynamical systems, mechanics and control. I am interested in the theoretical aspects of both geometric and statistical descriptions of transport in dynamical systems. Applications include fluid mixing in laminar flows, nonlinear vibration mitigation, model reduction of fluid dynamical systems, multi-agent/swarm control, and low-energy mission design in the three-body system.
