My research as a Project Assistant Professor (NAOJ Fellow) at the National Astronomical Observatory of Japan (working for NAOJ Chile and based at the Joint ALMA Observatory in Santiago, Chile) currently focuses on star formation, dust polarization, and polarization calibration with ALMA.
Prior to moving to Chile (with a two-month stopover at NAOJ HQ in Tokyo), I worked for three years as a Jansky Fellow of the National Radio Astronomy Observatory, based at the Harvard-Smithsonian Center for Astrophysics. There I published some of the first ALMA observations of magnetic fields toward extremely young, "Class 0" star-forming cores (see below).
Before moving back to the East Coast, I was a graduate student at the University of California, Berkeley, where I was the principal investigator (PI) of the TADPOL
collaboration, which comprised 25 astronomers from twelve institutions across
the U.S. and Canada. The main goal of the TADPOL survey was to
map the magnetic fields in the densest regions of cold, dusty star-forming clouds.
We used the 1 mm, dual-polarization receiver system at CARMA, a
millimeter-wave radio telescope near Bishop, CA.
The results from the TADPOL survey
(click here),
published in 2014,
show that the magnetic fields in a subset of the low-mass protostellar cores we observed
may have been wrapped up by core rotation,
and that overall, outflows and small-scale magnetic fields these objects are randomly aligned.
These results are consistent with the first results from the
TADPOL survey, which discussed the misalignment of magnetic fields and outflows
(click here).
Along with Dick Plambeck, a research astronomer at UC Berkeley, I tested,
installed, and calibrated the CARMA
dual-polarization receiver system; click here
for the publication that describes the receiver system in detail.
My research career began in the summer of 2005, when I worked as an NSF REU
intern with astronomy professor Dan Watson at the
University of Rochester,
analyzing a sample of Class 0 protostars observed by the Spitzer Space
Telescope. Our work was published in a Nature article
(click here) that
discussed the observational signatures of an accretion shock caused by
material falling from the protostellar envelope onto the deeply embedded
protostellar disk of the protostar NGC 1333-IRAS 4B.
