I focus on providing observational tests for low-mass star formation theories, particularly concerning mass accretion and angular momentum transfer. To investigate these physical processes, I have carried out surveys of low mass stars, both young and old, using spectroscopy and photometry at optical and near-infrared wavelengths. A full description of my past and current work is available in my research statement.
Thesis Work
Measuring properties of young, embedded stars in nearby star formation regions, and characterizing the mass function of low mass stars in the Galactic field.

Data Products
An archival gzipped tarfile containing the UW M star analysis pipeline ('the Hammer') is available here as hammer.tar.gz. This IDL code processes a list of input spectra by automatically estimating each object's spectral type and measuring activity and metallicity tracers in late type stars. Once automatic processing is complete, an interactive interface allows the user to manually tweak the final assigned spectral type through visual comparison with a set of templates. This distribution contains a README file to explain the usage of routine, as well as a small set of spectra and associated output files to demonstrate the usage of the code. A rudimentary documentation of the indices used to assign initial spectral type estimates is available in postscript form here.
Copies of the spectra analyzed in Hawley et al. 2002 are available as an archival tarfile. We have also created a smaller archive containing only the template spectra presented in Figure 5. The photometry for these objects is also available, and split into 3 groups: M0-M8 objects found in the Early Data Release, objects M9 and later newly discovered to be in the SDSS, and previously known MLT dwarves in the SDSS. Last, but not least, a generic README file has been written for those tables.
