Personal profile

Professional Information

My group studies the cutest stars - big and cuddly protostars only 10,000 to 100,000 years old, before they turn punky and begin to fuse hydrogen into helium in their core in about 1 million years. These stars are surrounded by envelopes of dust and gas that give us direct evidence of how stars form and how early planetary systems are going to form.  Lately, we have been most excited about 1) how circumstellar disks evolve from the earliest stages and what impact the disk has on the evolution of planets via dust grain growth, and 2) the polarization of light from the circumstellar disk which arises from three mechanisms, aligned dust grains via magnetic field, aligned dust grains from radiation, and/or scattering.   

The sources we study are usually deeply embedded in gas and dust, which means that they can only be observed at wavelengths longer than 10 microns.   Thus, our  group typically utilizes ALMA, SOFIA, and VLA observations to peer into stellar nurseries.

However, lately I am also considering variability of sources in LSST.
