I am a fifth-year graduate student in Astronomy at Caltech, where my advisor is Shri Kulkarni. Beginning in Fall 2020, I will be a Miller Fellow at UC Berkeley.

For my thesis, I am using the Zwicky Transient Facility (ZTF) to investigate extreme endpoints of stellar evolution: explosions powered by a central engine (Ho et al. 2018, 2020a, 2020b), interaction with the surrounding environment (Ho et al. 2019b), or both (Ho et al. 2019a, Duffell & Ho 2019).

Before coming to Caltech, I spent a year on a Fulbright at the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany. There, I worked with Hans-Walter Rix, Melissa Ness, and David Hogg on The Cannon. By propagating information from a high-S/N, high-resolution survey to low-resolution, noisy spectra, we assembled the largest catalog of stellar masses and ages to-date (Ho et al. 2017a, Ho et al. 2017b) as well as the largest catalog of lithium-rich giant stars (Casey, Ho et al. 2019).

I obtained my B.S. in Physics at MIT. As an undergraduate, I spent two summers at the National Radio Astronomy Observatory (NRAO), working with Scott Ransom on using millisecond pulsars in the globular cluster Terzan 5 to measure small-scale structure in the magnetic field of the Milky Way.
