I am an Associate Professor in the Department of Astrophysical and Planetary Sciences (APS) at the University of Colorado Boulder, and a member of the Laboratory for Atmospheric and Space Physics (LASP).

In my research I study the hot, expanding outer atmospheres of the Sun and other stars. Using both theoretical models and observations, scientists are able to infer a great deal about the physical principles underlying these distant objects, adding to our knowledge of how the universe works as a whole. Understanding the Sun and its atmosphere is also a necessary precursor to being able to predict the Sun's long-term effects on the Earth's climate and local space environment.
