Research Interests

My primary research interest is the outer Solar System. In particular, I am using the blind stellar occultation survey technique to detect small (~1 km), distant objects in the Kuiper Belt and beyond. The size distribution and dynamical characteristics of these objects provide important clues to the formation history of the Solar System. The occultation technique is also uniquely suited to probe the region of 100 to 1000 AU from the Sun, where the discovery of Sedna implies that there may be many more objects that currently can not be discovered with any other astronomical technique. I am leading the development of TAOS II, a next generation occultation survey which will use an array of larger telescopes and be located at San Pedro Martir Observatory in Baja California, Mexico. The new survey will be more than a hundred times more powerful than the TAOS I survey, which will allow us to probe even smaller and more distant objects. We plan to start collecting data with the new survey in late 2017.
