Amadi Brians Chinonso, PhD, is a Space Geophysicist whose research lies at the critical intersection of Magnetosphere-Ionosphere coupling and Space Weather applications. Amadi is committed to the understanding of the complex dynamics of the upper atmosphere, specifically focusing on how ionospheric variability impacts modern technological infrastructure.
Dr. Amadi earned his PhD in Space Geophysics in 2024 from the National Institute for Space Research (INPE) in Brazil. His academic journey, which began with a Higher Diploma in Physics and Electronics, a BSc from Nnamdi Azikiwe University and an MSc from the University of Lagos, has been defined by a deep interest in equatorial ionosphere response to atmospheric and geomagnetic forcings. By utilizing high-performance frameworks such as WACCM-X and SAMI-3, he has successfully simulated plasma environments that are vital for spacecraft charging assessments and GNSS navigation accuracy.
In 2024, Dr. Amadi served as a SCOSTEP Visiting Fellow at the NASA Goddard Space Flight Center, where he worked alongside Dr. Jeff Klenzing to apply high-resolution Python visualization tools to SAMI-3 outputs. This followed fellowships at the National Center for Atmospheric Research (NCAR) and Los Alamos National Laboratory, where he evaluated the effects of geomagnetic storm phases on equatorial plasma bubbles—findings that carry heavy implications for operational system vulnerability.
Beyond simulation and data fusion, Dr. Amadi is a passionate advocate for science communication and capacity building. As the Program Director of BrianSpace, he is working to reach 5,000 students across Africa. His recent work includes the development of the "Equatorial Ionosphere for Under-served Students" jupyter book, an open-access training resource designed to democratize high-level geophysics training for the next generation of African scientists. Additionally, Amadi is leading the development of AI-powered space weather dashboards and chatbots.
His most recent publication in the Journal of Geophysical Research: Space Physics (2025) investigates the occurrence variability of severe scintillation, offering new insights into how meso-scale wave structures influence ionospheric variability. Dr. Amadi continues to serve the scientific community as a peer reviewer for JGR and through the design of interactive space weather dashboards.
