His research interests are focused on applying optimal control principles for achieving enhanced performance of dynamical systems with an emphasis on aerospace vehicles. In particular, he has performed research on designing low-thrust and impulsive spacecraft trajectories using shape-based and indirect/direct optimization methods. His research interests are on developing novel methods to facilitate numerical solutions to optimal control problems that arise in orbital mechanics, atmospheric flight and operating dynamical systems.
Our research is focused on solving optimal control problems related to non-linear dynamical systems. In particular, we solve problems in the fields of astrodynamics (low-thrust and impulsive space trajectory design), atmospheric flight (unmanned aerial vehicles, launch vehicles and Entry, Descent, and Landing systems), and renewable energy devices (wave energy convertors).
