Research Overview
The vast majority of the baryonic matter in the Universe is in the plasma state. At the Yoon Plasma Group, we explore the fundamental processes that govern plasma behavior across dramatically different environments, covering cosmic scales to laboratory experiments.
About Yoon Plasma Group
Our research focuses on understanding how plasmas self-organize, generate magnetic fields, and transfer energy through complex nonlinear processes. By developing novel theoretical frameworks and advanced numerical simulations, we seek to uncover the universal principles that connect seemingly disparate plasma environments.
We believe that the most profound insights emerge from the intersection of rigorous theoretical analysis, advanced numerical modeling, and careful comparison with experimental observations.
Research Philosophy
Our approach combines analytical theory, numerical simulation, experimental validation, and observational connections to push the boundaries of plasma physics understanding, with particular emphasis on developing predictive theories for complex plasma phenomena that span laboratory, space, and astrophysical environments.

Background
Foundation at Caltech
The group builds upon foundational work developed at Caltech's Bellan Plasma Group, where novel theoretical frameworks for magnetic reconnection were established, the origins of extreme ion heating during reconnection events were explained, and critical conditions for electromagnetic wave scattering of energetic electron beams were derived.
