Wave-particle interactions are vitally important in, and fundamental to plasma physics, with widespread applications to space and astrophysical phenomena. They link the generation and properties of waves and radiation with the heating, acceleration, and transport of plasma particles. The research program aims to develop theories tested with observational data that resolve four critical issues in space physics: (1) whether linear mode conversion is important, (2) why waves and radiation are typically bursty, (3) how heating and particle acceleration occur in magnetic reconnection regions such as the solar atmosphere, and (4) how to explain important solar, interplanetary, and magnetospheric radio phenomena that depend on both microscopic wave-particle physics and largescale source structure.

波粒相互作用在等离子体物理学中至关重要，是等离子体物理学的基础，广泛应用于空间和天体物理现象。它们将波和辐射的产生和性质与等离子体粒子的加热、加速和传输联系起来。该研究计划旨在开发用观测数据测试的理论，以解决空间物理学中的四个关键问题：（1）线性模式转换是否重要，（2）为什么波和辐射通常是突发的，（3）在磁重联区域（如太阳大气层）中如何发生加热和粒子加速，以及（4）如何解释重要的太阳，行星际，磁层射电现象依赖于微观波粒子物理学和大尺度源结构。
