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. I am interested in dynamical systems theory and its applications, broadly interpreted. My current and past work has been on aspects of fluid mechanics such mixing and scalar transport in laminar and turbulent flows,  efficient phase space transport in three-body problem, bifurcations in essentially nonlinear systems, data-driven methods for model reduction, and recently, topics at the intersection of nonlinear systems and 'optimal transport'.
