My research currently focuses on star formation, dust polarization, and millimeter
I am the principal investigator (PI) of the TADPOL collaboration, which comprises 25 astronomers from twelve institutions across the U.S. and Canada. The main goal of the TADPOL survey is to map the magnetic fields in the densest regions of cold, dusty star-forming clouds. We use 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) 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, and were published in the Astrophysical Journal (click here) in 2013.
Along with Dick Plambeck, a research astronomer at UC Berkeley, I tested, installed, and calibrated the CARMA dual-polarization receiver system, which has been available to all observers since the spring of 2012.
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.
