Dr. Ellen Howell received a Ph.D. from LPL in December, 1995. She moved to Puerto Rico and worked as a post-doc in the Geology Department of the University of Puerto Rico, Mayagüez. She then spent 14 years at the Arecibo Observatory as a staff scientist. Ellen specializes in remote sensing of asteroids and comets, and combining different types of data at different wavelengths. She studies thermal properties of near-Earth asteroids, radar imaging, and compositional spectroscopy. She also studies the coma of comets at radio wavelengths, for which the Arecibo Observatory is especially well suited. Since returning to Tucson in August, she has been working on the OSIRIS-REx mission to Bennu, in the spectral analysis and imaging processing groups.
