What I do
I am a full professor and astronomer who is committed to the idea that science is for everyone and science needs everyone! I work to make my professional communities accessible, equitable, inclusive, and welcoming for all students.
astronomy, astrophysics, computational physics
I earned my Ph.D. in Astronomy from the University of Wisconsin and held a National Science Foundation Astronomy & Astrophysics Postdoctoral Fellowship at UC Berkeley before joining the faculty at DU. My research interests focus on the late stages of massive stellar evolution, in particular on the role of binary stars in shaping supernova explosions. I use a combination of observational spectropolarimetry and 3-D computational modeling to explore these research questions. I also see my roles as an educator and mentor as a vital part of my scholarship. In all these arenas, I work to expand opportunities and remove barriers to participation in physics and astronomy for people from historically underrepresented groups.

I use a combination of observational spectropolarimetry and numerical/computational Monte Carlo radiative transfer simulations to characterize the circumstellar material around massive binary stars and supernovae.
