Ph.D. Planetary Sciences, University of Arizona, 2005 

Dissertation: “Remote Sensing of Thermally Induced Activity on Io and Mars”

B.S. Mathematics, University of Arizona, 2000

Professional Statement

Dr. Milazzo is experienced with visible and near-infrared remote sensing as well as planetary data processing. He has: contributed to making mosaics of the Magellan radar data at Venus, worked with the Solid State Imaging (SSI) team of NASA’s Galileo spacecraft in orbit at Jupiter in the role of planning, processing, mosaicing, and interpreting images of the active volcanoes on Io and tectonic activity on Europa; worked with the Thermal Emission Imaging System (THEMIS) team of NASA’s Mars Odyssey spacecraft in the role of interpreting and calibrating visible and infrared images of the surface of Mars; planned flyby observations of Io for the Cassini Imaging Science Subsystem (ISS) team, planned first-cut observations of Saturn's icy moons and Titan; planned and analyzed very high-resolution (25-cm ground scale) imaging of the Martian surface with the High Resolution Imaging Science Experiment (HiRISE) camera onboard NASA’s Mars Reconnaissance Orbiter (MRO) spacecraft.


Dr. Milazzo has spent the past several years focusing on education and inclusivity of the sciences. This includes managing the USGS portion of the NASA-funded PLANETS project, which is a partnership between the USGS Astrogeology Science Center, Northern Arizona University, and the Boston Museum of Science to develop out-of-school-time planetary science and engineering curricular materials for middle school-aged youth.
Dr. Milazzo has also created the USGS StepUp! Employee Empowerment Strategies series of workshops designed to improve bystander intervention skills and strategies for professionals working in the sciences. This workshop is based on the University of Arizona's StepUp! Bystander Intervention program but has been modified to better fit a professional environment, including conferences and the office environment.

In addition, Dr. Milazzo has experience with numerical modeling of the cooling of lava flows. He has written software to: assist in his analysis of lava–sulfur-dioxide interactions at the surface of Io and the role of those interactions in the production of Io’s giant volcanic plumes; model the lava–water interactions and the role of those interactions in the formation of columnar jointing on the surface of Earth and Mars; model the Martian near-surface heat flow due to daily and seasonal changes. Dr. Milazzo has contributed significantly to the development of planetary remote sensing, image processing, cartographic mapping, and calibration techniques for a variety of missions and data types, including: MRO, MGS, and Odyssey (Mars); Cassini, Galileo and Voyager (Io, Europa, Ganymede, and Callisto); and at various geological field sites on the Earth, including in Hawai’i, Utah, and Arizona.

Dr. Milazzo is excited to give classroom and public lectures, university seminars, and the like. In addition, he is happy to review manuscripts and proposals, formally or informally.
