I am a second-year graduate student working with Joel Ong and Jen van Saders on SPB stars. During my first year, worked on type Ia supernovae with Ben Shappee. My undergraduate research was centered on globular clusters.


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