Current research is focused on incorporating unpredictable/chaotic behavior into optimal trajectories and trajectory optimization of swarms using indirect methods. Prior work includes development of a GPU-accelerated optimal control solver using the multiple shooting method which has significant performance gains over the state-of-the-art direct methods for trajectory optimization.

Investigating the feasibility and benefits of performing human-class Mars missions using slender entry vehicles. This exploration architecture enables the use of highly maneuverable systems without configuration change. Deceleration is accomplished using lift to direct the motion of the vehicle upward such that gravity provides terminal deceleration. Research also encompasses incorporating risk analysis within traditional design environments.

Investigating the feasibility of convex optimization methods in hypersonic missions such as Earth reentry and Mars EDL. Current efforts are focused on convexification of highly constrained trajectory optimization problems which are traditionally solved as nonlinear optimal control problems. Emphasis is placed on potential onboard guidance applications.

Developed a mission architecture to support the recovery of launch vehicle stages using inflatables. The inflatables are capable of providing a benign entry environment while also potentially serving as a means of atmospheric buoyancy through their large size. Research demonstrated the feasibility of returning first stages to Cape Canaveral within a month. The trajectory of the recovered stage is controlled by leveraging the various wind directions at different altitudes. Atmospheric wind information was provided by Earth GRAM, trajectory optimization was performed using dynamic programming, and system sizing was performed using current inflatable research supporting planetary exploration.
