Jason Parisi

Staff Research Physicist

Jason is a staff research physicist at Princeton Plasma Physics Laboratory. He obtained his B.S. in Physics from Yale University in 2016 and completed his Ph.D. in Theoretical Physics at the University of Oxford in 2020. During his doctoral studies, he focused on investigating gyrokinetic instability in the tokamak pedestal by combining theoretical and computational approaches. Working with Prof. Felix Parra, he found a new type of electron temperature gradient instability, which has been verified through gyrokinetic simulations in various tokamaks, including JET, DIII-D, and NSTX. As a Culham Fusion Research Fellow at the Culham Centre for Fusion Energy from 2020 to 2021, Jason used nonlinear gyrokinetic simulations to demonstrate the relationship between turbulent transport and magnetic geometry in tokamak pedestals. At PPPL, Jason’s primary focus is on developing a predictive model for the tokamak pedestal width and height using gyrokinetics. In particular, he aims to explain the distinct scaling laws observed in spherical and regular aspect ratio tokamak pedestals, with implications for fusion pilot plant design.
