Shibaji Chakraborty

I am a Research Scientist at the Space and Atmospheric Instrumentation Lab (SAIL) at Embry-Riddle Aeronautical University. My research focuses on understanding how transient solar events — flares, coronal mass ejections, and solar eclipses — impact the Earth's Magnetosphere-Ionosphere-Thermosphere (MIT) system.

I combine ground-based HF radar observations (SuperDARN network), satellite data, physics-based simulations (WACCM-X, TIE-GCM), and machine learning to characterize space weather impacts on radio communications, navigation systems, and critical infrastructure. I am Lead PI on an NSF-funded collaborative investigation of eclipse-driven ionospheric dynamics and co-investigator on multiple NASA awards.

Prior to ERAU, I was a Postdoctoral Associate at Virginia Tech (2021–2024), where I received my Ph.D. in Electrical Engineering (2021) and M.A. in Data Analytics (2020). Before academia, I spent nearly five years as an IT Analyst at Tata Consultancy Services Innovation Labs.

Beyond space physics, I am expanding into broader data analytics and complex systems, and writing for general audiences about science that matters — from solar superstorms to the hidden vulnerabilities of global internet infrastructure.
