Justin Ball is a post-doctoral researcher studying theoretical plasma physics and nuclear fusion energy. His research primarily focuses on the effect of plasma shaping on turbulence in tokamaks. Additionally, he is an avid fusion science communicator via magazine articles, lectures, podcasts, and a popular science book.
He holds a Bachelor's degree from the University of Michigan and a Master's from MIT, both in Nuclear Engineering. In 2016, he completed a PhD in Theoretical Physics at the University of Oxford and received the European Physical Society Plasma Physics PhD Research Award. Previously, he has worked at a nuclear power plant, a nuclear navy research laboratory, and a nuclear weapons laboratory.
