Current Project: Temperature separation in high energy density plasma.

Harry graduated from Harvey Mudd College (HMC) in 2020 with a degree in physics. On the side, he dabbled in "pretengineering" and various campus activities. He tutored for physics courses in the HMC core sequence, organized outreach events for elementary and high school children, and worked as a tour guide. He first became interested in plasma physics in his sophomore year when he joined Albert Dato's engineering lab and worked on an RF plasma source for gas-phase graphene synthesis. He shamelessly acknowledges being first drawn to the lab as a chance to play with interesting electronics and bright, colorful plasmas. Further developing and testing this reactor became his senior thesis, working with Tom Donnelly. In summer 2019, he worked as a SULI intern at PPPL with Rob Goldston, helping to build a robot for monitoring fission fuel enrichment, where he learned that plasma research also involves exciting scientific problems! How convenient!

At Princeton, Harry first worked with Yevgeny Raitses and Sophia Gershman on low-temperature plasma experiments for disinfection and ammonia synthesis. In his second year, he began work with Nat Fisch on strongly coupled plasma; after some iteration, this has broadened and turned into his thesis project. Currently, this work centers on effects that appear when high energy density plasma is in a quasi-equilibrium state, such as when electrons and ions are thermally distributed but at different temperatures. Applications include inertial confinement fusion, but the topic also relates to a variety of fundamental physics problems.

In his spare time, Harry likes cooking, board games, and walks in the woods (generic hobbies, but they're classics for a reason!). He also loves learning about languages and has taken classes in Russian, German, and linguistics in his time at Princeton. He is so so sorry for writing in the third person... please feel free to reach out for any reason! I'm (he's) happy to talk about the Program, grad school at Princeton, or just physics more generally!
