Biography

Before UT, Dr. Montgomery completed postdoctoral positions at the Institute of Astronomy in Vienna, Austria, and the Institute of Astronomy in Cambridge, UK. Before that, he completed his Ph.D. in 1998 at the University of Texas at Austin, working with Dr. Don Winget on the evolution and pulsation of crystallizing white dwarf stars. Since 2009, he has run the FRI course in Astronomy, which gets students started in the research careers in their freshman year of school. His recent research has focused more on laboratory astrophysics questions, and he is currently the Deputy Director of the Wootton Center for Astrophysical Plasma Properties.
