About

I like all things physics. My emphasis is in fluid and plasma dynamics, control theory and optimization. I have applied this to the re-entry trajectories of hypersonic vehicles, high-altitude trapped radiation propagation, satellite GNC, CFD and adjoint-based shape optimization of fans and turbines, helicopter noise suppression, ignition over-pressure suppression for launch vehicles using water droplets, fusion plasma modeling and control and atmospheric laser propagation and off-axis characterization. Since launching my R&D company I have directed more than $1M of research with a team as large as 6, myself included. Our largest projects include a satellite management and decision-making tool for the Space Force and the most efficient hydrokinetic riverine turbine for ARPA-E.
