Research
I am currently studying magnetic interactions between young stars and their surrounding disks. Theories of low-mass star formation suggest these interactions govern the physics of mass accretion and angular momentum transfer in the youngest stars.
To study this complex and time-dependent phenomenon, I analyze photometry and spectroscopy at wavelengths stretching from visual light to the radio, using dedicated observations in concert
with data from large survey projects.
I also study low-mass stars at later ages; I am carrying out a census of stars in the local galactic neighborhood, and tracing the properties and evolution of stellar magnetic fields over time. I am currently preparing a new description of my
research program, but a slightly outdated (almost two years old!) copy of my research statement is still available.

Data Products
Resources from Covey et al. 2007: The 'Hammer' spectral typing and analysis software; the `High Quality' sample of SDSS/2MASS matches (superclean.fits); the full sample, with calculated color distances (colordistances.fits); and machine-readable tables of the properties of the median stellar locus (medianlocus.tbl), synthetic SDSS/2MASS photometry of Pickles (1998) spectral standards with solar (SolarPickles.tbl) and non-solar (NonSolarPickles.tbl) metallicites;
Spectra and photometry from Hawley et al. 2002: SDSS M/L spectral templates from Figure 5, as well as the complete spectroscopic sample. Photometry for these objects is also available in three tables (with a generic README file): M0-M8 objects with Early Data Release spectra, objects M9 and later identified by Hawley et al. 2002, and previously known SDSS MLT dwarves.
