Parker Roberts
PhD Candidate
NASA Space Technology Graduate Research Opportunity Fellow
Parker graduated from Berry College in May 2020 with a B.S. in Physics and Mathematics. He joined PEPL in the fall of 2020 as a Ph.D. student in Aerospace Engineering. He spent two summers working with the Jet Propulsion Laboratory on validation testing of the Hall-Effect Rocket with Magnetic Shielding (HERMeS) for the Lunar Gateway spacecraft. His current research focuses on investigating particle transport, oscillations, and facility effects in high-power Hall thrusters using non-invasive laser plasma diagnostics including Laser-Induced Fluorescence and Incoherent Thomson Scattering.

Braden Oh
PhD Pre-Candidate
National Science Foundation Fellow
Braden graduated from Olin College of Engineering with a B.S. in Engineering Physics and a minor in vocal performance. There he founded the Olin Plasma Engineering Lab which demonstrated the first steady state Hall thruster built by a fully undergraduate team. He joined PEPL in the fall of 2023 as an Aerospace Engineering Ph.D. student. His current research focuses on using condensible propellants to achieve ultrahigh current densities in Hall thrusters.

Miron Liu
PhD Pre-Candidate
Miron Liu earned his B.S. in Aerospace Engineering from the University of Illinois Urbana-Champaign (UIUC) in Spring 2023. As an undergrad he worked on electrospray diagnostics in the UIUC Electric Propulsion Laboratory. He joined PEPL as a PhD student in Fall 2023. His research interests include low-temperature plasma diagnostics, plasma wave-induced anomalous transport, and life-limiting mechanisms of electric propulsion (EP) devices. His current work focuses on characterizing key wave properties using novel experimental methodologies and diagnostics with the goal of developing prescriptive mitigation strategies to eliminate pole erosion in magnetically shielded Hall thrusters.
