About the Lab
Professor In-Soo Jeon's research lab focuses on host-pathogen interactions, particularly the immunological mechanisms underlying bacterial infections such as scrub typhus caused by *Orientia tsutsugamushi*. The lab investigates dendritic cell responses during infection, emphasizing innate immune activation and antigen presentation. Additionally, the lab contributes to space weather research by analyzing high-energy solar proton events using deep-space spacecraft data, such as those from the Psyche mission. This interdisciplinary approach bridges infectious disease immunology and heliophysics.

2Orientia tsutsugamushi, a gram-negative bacterium, causes severe acute febrile illness in humans. Despite this danger, the route of infection, infectivity, and protective mechanisms of the host’s immune response to O. tsutsugamushi are unclear. Dendritic cells (DCs) are one of the most important cell types in bridging the innate and adaptive immune responses. In this study, we observed that O. tsutsugamushi infects and replicates in monocyte-derived DCs (MODCs). During infection and replication,
Abstract We report new measurements of high‐energy protons ejected by the sun during the May 2024 Ganon superstorm. Our observations were made by the Neutron Spectrometer (NS) on the Psyche spacecraft, which was located at a solar distance of approximately 2 AU and a Sun‐Earth‐Probe separation angle of 75°. This unique vantage point can provide new insights into the nature of this exceptional space weather event. Our observations validated predictions from the WSA‐ENLIL heliospheric model, which
