Research & Publications

Research Interests

My primary research interests include supernova cosmology and type Ia supernova (SN Ia) progenitors. I am also interested in light echoes, other binary white dwarf systems (CVs, mergers, ELMs, etc.), and brown dwarfs.

Supernova Cosmology

The value of the Hubble Constant (H0) as measured using SNe Ia distances and the CMB differ by ~5σ. I use surface brightness fluctuations to calibrate distances to fainter, faster-declining SNe Ia to test if SNe Ia systematics can resolve the tension.

Light Echoes & SNe Ia Progenitors

The exact progenitor systems and their relative occurrence rates are not well known. I use light echoes as a probe of the local dust environments around SNe Ia to search for circumstellar material that can tell us about the progenitors.

White Dwarf Binaries

In addition to SNe Ia progenitors, I am also interested in other white dwarf (WD) binary systems. I have assisted with observations of the first known WD pulsar (AR Sco) and a WD merger candidate now tied to an ancient SN Iax (J005311). I was also part of a search for evidence of debris disks around ELM WDs.

Directly Imaged Brown Dwarfs

At least two of a brown dwarf's (BD) luminosity, mass, and age must be known in order to uniquely characterize the brown dwarf. I use directly imaged BDs with all three properties measured to benchmark substellar evolutionary models.
