I am a second-year graduate student working with Joel Ong and Jen van Saders on the asteroseismology of gravity-mode pulsators. My other work with Ben Shappee focuses on observations of type Ia supernovae to improve our understanding of their progenitor systems.


My research background includes asteroseismology, type Ia supernovae, and globular clusters. My publications in those areas can be found below.
