I am a Research Scientist at Southwest Research Institute in San Antonio, Texas. I got both my master’s degree and my PhD in Astronomy at the University of Padua, Italy, where Galileo discovered the Jovian moons and ushered the modern era of astronomy, with a thesis on (among other objects)… Io, one of the Galilean moons. I study the exospheres of airless bodies in the Solar System: the Moon, Io, Mercury… you name it. I combine Monte Carlo modeling with data analysis (spectroscopy), with data taken both from the ground and from space. I am deputy project scientist of LAMP, UV spectrograph on board the Lunar Reconnaissance Orbiter, and I am on the team of Strofio, a mass spectrometer that is currently en route to Mercury on BepiColombo.

Besides astronomy (especially planetary science), my passions are (in no particular order): movies (including some blockbusters), geography, traveling, hiking, Queen, and photography.
Paul Byrne (@ThePlanetaryGuy) is Assistant Professor of Planetary Science at North Carolina State University. He graduated with a Ph.D. in planetary geology from Trinity College Dublin in 2010 and participated in the MESSENGER mission as a postdoctoral fellow from 2011 to 2015 at the Carnegie Institution’s Department of Terrestrial Magnetism and the Lunar and Planetary Institute. Through a combination of remotely sensed data, physical and numerical modeling, and fieldwork at analog sites, his research focuses on the links between surface and interior processes on rocky and icy bodies in this solar System and beyond.
Tim Holt (@timholtastro )is an Australian PhD candidate at the Centre for Astrophysics, University of Southern Queensland. The commute is a bit far though, as he currently has an office at the Southwest Research Institute in Boulder, CO, USA. He is in his second year of a PhD working on the Taxonomy and Dynamics of small Solar system bodies, with a primary focus on the Jovian Trojan Asteroids. There are two aspects to this work, using n-body simulations to look at the dynamics of families, and borrowing a technique from biology, cladistics for the taxonomy.
In a previous life, Tim spent his undergraduate at the University of Queensland digging up Dinosaurs. There were some diversions in retail, and a stint as a high school science teacher, before eventually settling in Astronomy with Swinburne Astronomy Online.
Besides science, Tim enjoys Sci-fi in it’s many forms, especially Internet Spaceships (Eve Online), books, IT stuff, board games and traveling.
Theodore (“Teddy”) Kareta (@teddykareta) is a 1st year graduate student at the University of Arizona’s Lunar and Planetary Laboratory. Teddy studies the evolution of small bodies (e.g. comets, asteroids) with telescopic and spacecraft data, such as from the NASA IRTF, the ESA’s Rosetta mission, and (in a few months) NASA’s OSIRIS-REx mission. Specifically, he is interested in studying the surfaces of small bodies to understand something about their history – and how they will continue to change into the future. Before moving to the desert of southern Arizona, he completed a BS in Physics and Astronomy at the University of Massachusetts, Amherst.
Outside of work, Teddy enjoys biking, outreach, and watching bad movies with his friends.
Helen Maynard-Casely is a Planetary Scientist based at the Australian Nuclear Science and Technology Organisation (ANSTO) where she uses the neutrons and synchrotron x-rays to investigate the materials that make up our solar system. She has a PhD in high-pressure physics from the University of Edinburgh and has been lucky enough to have collected data in facilities all over the world, blowing up a few diamonds along the way. Currently she’s trying to characterise all the ‘minerals’ that would form on Europa and Titan. Always keen to tell anyone who’ll listen about planetary science, she tweets @Helen_E_MC.
