Research Interests

I am an assistant research scientist at the Center for Cosmology and Particle Physics at New York University, where I work with Prof. Maryam Modjaz.

I am mainly interested in discovering what type of star leads to a thermonuclear, or "Type Ia," supernova. I do this mainly by measuring the rates of explosion of supernovae that I discover in both imaging-based surveys (such as the Subaru Deep Field survey and CLASH) and in spectroscopic surveys, such as the SDSS. I am also interested in finding new ways to discover transient phenomena in large databases using advanced data science methods.

In 2012, my PhD thesis was one of 12 animated by Jorge Cham of PhD Comics:

In 2016, we discovered the first evidence of the decay of 57Co in a Type Ia supernova:
