Dr. Hwang’s exceptional record of scientific innovation, leadership, and service positions him as a standout candidate for top research honors. Professional Profile Scopus Profile Education Dr. Kyoung-Joo Hwang’s academic foundation in space physics is rooted in a rigorous and prestigious educational journey. He graduated as the top student with a Bachelor of Science in Physics from Korea University in 1997. He then earned his Master’s degree in Space Physics from the Korea Advanced Institute of Science and Technology (KAIST) in 1999, where he conducted 3D MHD simulations related to magnetic reconnection and coronal mass ejections. His academic path culminated in a Ph.D. in Space Physics from Dartmouth College in 2006. There, he contributed to auroral physics research and participated in NASA’s Sounding Rocket experiments. Throughout his education, Dr. Hwang focused on both theoretical and observational plasma physics, preparing him for a career in magnetospheric science. This well-rounded academic background laid a strong foundation for his later success in researchEarth and Planetary Sciences, spacecraft mission development, and scientific leadership in the field of heliophysics and magnetospheric plasma dynamics. Experience Dr. Kyoung-Joo Hwang has built an exceptional professional career through roles that span elite research institutions and mission-critical NASA programs. He is currently a Principal Scientist at Southwest Research Institute (SwRI), where he leads major NASA CubeSat and MIDEX mission proposals. Prior to SwRI, he held prominent research positions at NASA Goddard Space Flight Center and the University of Maryland, contributing to flagship missions such as MMS, THEMIS, Cluster, and Van Allen Probes. His earlier appointments at LASP (University of Colorado) and Dartmouth College involved both data analysis and simulation work, including early-stage mission hardware efforts. Across these roles, he has led research in magnetospheric reconnection, plasma instabilities, and wave-particle dynamics. His leadership is further reflected in his role as a proposal PI on multi-million-dollar funded projects and as team leader for multiple International Space Science Institute (ISSI) programs. Dr. Hwang’s career reflects scientific depth, mission integration, and global collaboration. Research Focus on Earth and Planetary Sciences Dr. Kyoung-Joo Hwang’s research interests focus on fundamental processes governing space plasma dynamics, particularly magnetic reconnection, Kelvin-Helmholtz instabilities, dipolarization fronts, and magnetosphere-ionosphere coupling. His work combines spacecraft data analysis with advanced simulations to explore multi-scale plasma phenomena in Earth’s magnetosphere. He has extensively used data from missions such as MMS, THEMIS, Cluster, and FAST to investigate magnetic field dynamics, wave structures, and particle acceleration. His interest also extends to spacecraft instrumentation and data validation, ensuring the accuracy of datasets for community-wide scientific use. Dr. Hwang’s interdisciplinary approach—blending theory, modeling, and observation—has helped identify and characterize complex space weather drivers and plasma turbulence mechanisms. Through leadership in NASA mission concept proposals and international teams (ISSI), he aims to advance understanding of cross-scale processes that impact space weather forecasting and magnetospheric science. His research continues to push the boundaries of knowledge in heliophysics and geospace environments. Award and Honor While specific awards are not explicitly listed in his CV, Dr. Kyoung-Joo Hwang has received significant honors and recognition through leadership roles, high-impact publications, and competitive grant awards. His work has been repeatedly highlighted by major agencies such as NASA and ESA, including featured publications in AGU Research Spotlight, NASA’s Heliopress Highlights, and ESA science news. As a reviewer for over 100 scientific papers and ~40 major proposals, he is recognized as a trusted expert in the field. He has been selected as a Topic Editor for Frontiers in Astronomy and Space Sciences, a sign of his leadership in the global scientific community. Leading multiple ISSI international teams also reflects peer recognition of his expertise. His successful PI roles on numerous NASA and NSF-funded projects further demonstrate professional acknowledgment of his scientific innovation.
