Scranton Researchers Awarded NASA Grant Totaling More Than a Half-Million Dollars

A research team from The University of Scranton has set out to answer a few questions whose answers may benefit communication systems around the world.

NASA's Heliophysics Citizen Science Investigations program awarded the University a $568,117 grant to discover more information about the weather in space and how those conditions affect the reliability of high-frequency communication systems used on Earth.

The three-year project, titled "Ionospheric Model Validation and Development of an Open-Source High Frequency Ray-Tracing Toolkit" is led by Kornyanat "Kukkai" Hozumi, Ph.D., research scientist at Scranton. Dr. Hozumi is serving as the principal investigator with collaborators Nathaniel Frissell, Ph.D., associate professor of physics and engineering, and Mark Fenner, Ph.D., assistant professor of computing sciences, on the interdisciplinary team. The grant was awarded in February 2026 with work slated to continue through January 2029.

The Scranton team is researching how radio waves travel through the ionosphere, a region of the upper atmosphere that enables long-distance radio communication. Disturbances caused by solar activity can disrupt these signals, affecting aviation, emergency alerts, military operations and global radio networks.

Researchers will develop a freely available, open-source software toolkit capable of modeling radio wave propagation in three dimensions. This represents a significant advancement from the earlier two-dimensional tools.

Amateur radio operators from within the influential and prolific Ham Radio Science Citizen Investigation (HamSCI) community will test tools and contribute data that will then be analyzed by the researchers.

While several aspects of the work have already been outlined, the project centers on four key goals: 1. Developing a three-dimensional, open-source, high-frequency ray-tracing toolkit; 2. Validating leading ionospheric models using data from the global HamSCI network; 3. Studying space weather's effects on radio signals; 4. Broadening access to data through public seminars and other avenues that support researchers, students and amateur radio operators.

Earlier this year, The University of Scranton received a three-year, $600,000 grant from the Office of Naval Research regarding ionospheric research.
