Dr. Phillip Chamberlin is a Research Astrophysicist at the Solar Physics Laboratory, Code 671, located at NASA Goddard Space Flight Center. His research is focused primarily on measuring and modeling of the solar X-ray and ultraviolet irradiance. Dr. Chamberlin led the development of the Flare Irradiance Spectral Model (FISM), which not only improved the ability to empirically model the solar cycle and solar rotation irradiance variations in the Vacuum Ultraviolet wavelengths (VUV; 0.1-190 nm), but also added the ability to model the irradiance variations due to solar flares. Dr. Chamberlin has also been involved with various tasks on six sounding rocket payloads and continues to be involved with the TIMED SEE and SDO EVE data analysis, as well as the development of the GOES-R EXIS instruments (XRS and EUVS) and the MAVEN LPW-EUV instrument. He is also currently a Deputy Project Scientist for the Solar Dynamics Observatory (SDO).
