Career Objective

To make the best possible use of my background in scientific computing, physical modeling, numerical simulation, optimization, control, and dynamical systems. I recently completed my Ph.D. in Physics at UC Santa Barbara, where I collaborated with an experimental Terahertz physics research group. I additionally collaborated with an applied mathematics research group based in Madrid, Spain. Prior to graduate school, I developed trajectory design algorithms as an intern at Jet Propulsion Laboratory. With the recent completion of my formal education in theoretical and computational physics, I look forward to beginning the next chapter of my professional career. Education and Experience

2013–2017 Ph.D., Physics, UC Santa Barbara
