My research interests are primarily concerned with the study of brown dwarfs, low mass objects that cannot sustain stable Hydrogen fusion. In 2006, I initiated the Brown Dwarf Kinematics Project (BDKP) in order to use astrometric measurements to investigate fundamental physical properties of the brown dwarf population. Since that time, myself and collaborators have been collecting proper motions, parallaxes, and radial velocities for all brown dwarfs within 20pc as well as more distant objects of specific scientific interest (e.g low-surface gravity, subdwarfs, or extreme photometric outliers). The first major papers to emerge from the BDKP are:

At present, we have continuing astrometric programs in both South America (Chile) and North America (Arizona) to measure parallaxes and proper motions for both published and unpublished sources.
