Dr. Alex Harrison Parker

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.

Chasing stellar occultations in Argentina.

Dr. Parker is an expert in observational, theoretical, statistical, and instrumentation methodologies for exploring the origin and history of the solar system, with a particular focus on its minor planet populations. His publication record includes research on asteroid family physical characteristics, Kuiper Belt dynamics, the properties of the Pluto system as seen by New Horizons, computational optimization techniques for minor planet discovery, statistical methodologies for characterizing the lunar cratering history, and more. Since his PhD work on the characteristics of Kuiper Belt binary systems and their implications for the origin and evolution of the outer solar system, Dr. Parker has been engaged in efforts to enhance and enable planetary exploration. He surveyed the Kuiper Belt for a post-Pluto target for the New Horizons mission (leading to co-discovery of the extended mission target Arrokoth). He is now PI of the largest-ever solar system program on the Hubble Space Telescope, the Solar System Origins Legacy Survey, and he directs a NASA SSERVI node for exploration technology development, Project ESPRESSO
