Everything
else

I am a doctoral student in physics at the University of Texas (UT) at Dallas (in Richardson). My work is in space physics, the study of the space environment, encompassing realms from the ionosphere to the magnetosphere to interplanetary space.

Specifically, I am currently using data taken in the Earth's ionosphere by DMSP satellites to address questions about dynamics of the Earth's plasmasphere and the relationship of the plasmasphere to the Earth's radiation belts. My advisor is Phillip C. Anderson.

My M.S. is in physics from UT-El Paso in cooperation with UT-Brownsville. My work there in the relativity group was concerned with data analysis for gravitational wave detection. While there I worked on data analysis methods for triggered burst searches, on stochastic searches, and made two summer research visits to the LIGO-Livingston site.

My B.A. is in astronomy from UT-Austin. For three years I participated in the Dean's Scholars Program in the College of Natural Sciences.
