Research and Teaching Interests
Amy Gall is an Assistant Professor at Auburn University and a Research Associate at the Smithsonian Astrophysical Observatory (SAO). She works with the SAO electron beam ion trap (EBIT) facility to create and trap highly charged ions for spectroscopic investigations. Her research focuses on atomic processes in collisionally ionized plasmas, including electron impact ionization, excitation, and recombination. The atomic data she produces are used to test and benchmark the calculations that underpin astrophysical models. She is currently performing high-resolution X-ray and EUV measurements in support of next-generation missions such as XRISM, Athena, and MUSE, helping ensure these missions achieve their scientific goals.
