Tom Zega

Tom was born, raised, and educated in New Jersey. His background is in solid-state geochemistry (mineralogy/crystallography), cosmochemistry, and electron microscopy. His research interests are focused on the chemical and physical processes that occurred in ancient stars, the early solar system, and parent asteroids of meteorites. He uses transmission electron microscopy, analytical electron microscopy, focused ion-beam microscopy, and scanning transmission X-ray microscopy to determine crystal structure and chemistry of minerals within meteorites down to the atomic level. Such information is used to understand material properties and spatial relationships with surrounding mineral phases as a means to decipher astrophysical and cosmochemical histories.

Ken Domanik

Ken was born and raised in Wisconsin and graduated from the University of Wisconsin with an M.B.A. in 1982. After running a small computer consulting business for several years, he returned to school to pursue his life-long love of geology in more depth, and obtained a Ph.D. in Geology from Arizona State University in 1997. After managing the C.M. Scarfe Laboratory of Experimental Petrology in Edmonton Alberta, he returned to Arizona to manage the University of Arizona Electron Microprobe Laboratory in 1999. Ken's research interests include experimental petrology, electron microscopy, igneous and metamorphic petrology, Precambrian geology, the origin of achondrite meteorites, and the geology of the North American Cordillera and Lake Superior regions.

Dolores Hill

Dolores has had a lifelong interest in amateur astronomy and meteorites. She has analyzed and studied meteorites at LPL since 1981, beginning with rims of individual chondrules in type 3 chondrites and Wark-Lovering rims of Allende CAls (Calcium-Aluminum-rich Inclusions) with Dr. Bill Boynton, Dr. Laurel Wilkening, (and Dr. David Wark). Specializing in neutron activation analysis (using gamma ray spectroscopy), radiochemistry of rare earth elements, and electron microprobe techniques, she has been privileged to analyze samples of many famous and rare meteorites. She analyzes and classifies meteorites, supports LPL meteorite research activities and laboratory safety, assists graduate students and other researchers. She enjoys sharing the excitement of meteorite research through talks and providing hands-on meteorite opportunities for school groups, astronomy clubs, and special public events. Dolores is a member of the Education and Public Outreach Team for the NASA OSIRIS-REx asteroid sample return mission to Potentially Hazardous Asteroid (101955) 1999 RQ36. She is an OSIRIS-REx Ambassador, assists science team members, and is co-lead with Carl Hergenrother, for Target Asteroids! a new citizen science project and Target NE0s!, a new Astronomical League observing program.

Michelle Thompson

Michelle Thompson is a 5th year PhD student in Planetary Sciences at the Lunar and Planetary Laboratory. She originates from a small town in Ontario, Canada and completed her undergraduate studies at Queen's University in Canada, finishing a double degree in geological Engineering and biology. After completing a summer internship at NASA's Johnson Space Center, she became interested in cosmochemistry and planetary materials. Her current research focus is understanding space weathering of asteroidal and lunar soils by analyzing microchemistry and crystal structure.

Hannah Tanquary

Hannah is a 3rd year PhD student in Planetary Sciences at the Lunar and Planetary Laboratory. She earned a bachelor's degree in physics from Eastern Illinois University. Her research involves microanalysis of calcium-aluminum-rich inclusions in primitive meteorites.

Claudia Ramirez

Claudia is a 3rd year undergraduate student in the UA Materials Science & Engineering (MSE) Department. She’s originally from Lima, Peru, but grew up in New Jersey and Arizona. She is currently conducting research at LPL through the UA/NASA Space Grant Program, focusing in on the convergence between MSE and Planetary Sciences.

Diana Bolser, M.S. Chemistry 2014

Diana Bolser was a graduate student in the Department of Chemistry and Biochemistry at the University of Arizona. Originally from St. Louis, Missouri, she completed her undergraduate degree in physics at the University of Missouri-Columbia. Her research interests include understanding the thermodynamic histories and crystal-chemical properties of calcium-aluminum-rich inclusions (CAls) and presolar grains contained in primitive meteorites. For her work, she uses a variety of high-resolution analytical techniques including focused ion beam-scanning electron microscopy (FIB-SEM), transmission electron microscopy (TEM), and X-ray absorption near edge structure (XANES) spectroscopy. In her free time, Diana enjoys practicing yoga, baking, and watching True Blood.
