His research interests include the physics of the corona and solar wind, especially modeling them for both basic and applied (e.g., space weather forecasting) purposes. Dr. Arge is the lead developer of the Wang-Sheeley-Arge (WSA) coronal and solar wind model, which along with the Enlil solar wind model, was transitioned into operations at the National Weather Service (NWS) in 2011. The coupled WSA+Enlil model is the first space weather model to be transitioned to operations at the NWS. Dr. Arge is a member of the American Astronomical Society (AAS), the Solar Physics Division of AAS, and American Geophysical Union (AGU).
