Research scientist in planetary astronomy at the Southwest Research Institute, supporting NASA's New Horizons mission to Pluto, and developing the post-Pluto mission into the Kuiper Belt. Expert in the dynamics of binary minor planets, detection and characterization of trans-Neptunian objects, and the origin of the architecture of our Solar System.
The Flicker cubesat mission proposal was developed for the first NASA SIMPLEx call for planetary science cubesat missions. It would be an innovative 6U observatory carrying three telescopes with ultra-fast wide-field cameras to catch the momentary flicker of light when a distant object in the Kuiper Belt briefly occults a background star.

Read MoreImpact crater records across the solar system can provide powerful insights into the populations of objects bombarding these surfaces.
Read MoreIf New Horizons was to visit any worlds beyond Pluto, they would have to be searched for in the years after the mission left Earth. The challenge of finding a tiny, faint Kuiper Belt Object target for the mission was compounded by the location where targetable objects resided in the sky: directly in line with the core of our galaxy, in some of the most crowded star fields in the sky.
Read MoreThe regolith covering most asteroids has high magnetic susceptibility, and thus it can be physically manipulated with a magnetic field. In the low-g surface environment, magnetic grapples could anchor landers, mobilize robots, or enable highly efficient sample collection.
