Education: B.S. Physics, Georgia Tech, 2000 M.S. Astronomy, University of Florida, 2003 Ph.D Astronomy, University of Florida (in progress, expected Summer 2009) Awards: 2006 NASA Graduate Student Research Program Fellow 2007 NASA GSRP Fellow 2008 NASA GSRP Fellow Research: THESIS: The dynamical structure and formation of the zodiacal cloud dust bands. Determining the structure and sources of the zodiacal cloud through a dynamical investigation of asteroidal dust particles in the inner solar system. INTERESTS: Dynamical evolution of dust, particle break-up, resonant trapping, dust production in debris disks systems, dynamical structure of disks, temporal variations of debris disks from dynamical effects, solar system dynamics, resonant structures, asteroid disruptions.
