Dr. Michael Nolan returned to LPL in July as a Senior Research Scientist after twenty years at the Arecibo Observatory in Arecibo, Puerto Rico. After graduating with a Ph.D. from LPL in 1995, Mike joined Cornell University as a post-doctoral researcher at the Arecibo Observatory, and stayed at Arecibo in a number of scientific, technical, and management roles, including Observatory Director from 2008 to 2011. His research concentrates on the structure and evolution of asteroids and planetary surfaces using radar imaging and numerical simulation. At LPL, he will be the Asteroid Geophysical Scientist for the OSIRIS-REx project, and will continue remote sensing and modeling research on asteroids.
