• Assistant Professor, Geoscience Department, University of Nevada, Las Vegas: January 2009 - Present • NASA Postdoctoral Fellow, NASA Postdoctoral Program, NASA Johnson Space Center: 2007-2008 Education • Ph.D., Dual-Title Ph.D. Degree Program in Geosciences and Astrobiology, Pennsylvania State University, University Park, PA: 2007 • Sc.B., Geology-Chemistry, Brown University, Providence, RI: 2000 Assistant Professor, University of Nevada, Las Vegas • GEOG 103: Physical Geography of Earth's Environment Teaching Assistant, Pennsylvania State University Adjunct Faculty, Boise State University • MATH 025: Elementary Algebra Laboratory Teaching Assistant, Brown University • CHEM 21: Introductory Chemistry I am currently looking for students to work with at both the MS and PhD levels. I have listed some potential projects below. If you are interested •Experiments, modeling and fieldwork to interpret changes in chemistry and mineralogy observed from both orbiters and landers on Mars •Analysis of the impact of microbe-mineral interactions on mineral dissolution and precipitation and elemental cycling. •Dissolution and precipitation rates of soil-forming secondary minerals including laboratory, field, and modeling components. Weathering plays a key role in many critical processes on Earth, including the formation of soils, the control of atmospheric CO2 concentrations over geological time scales, and water quality. Yet field weathering rates remain difficult to predict even when laboratory rates have been measured, and the effect of factors such as biological interactions, physical erosion, and climate are poorly understood. It is imperative to better understand this "Critical Zone" upon which life depends. The study of soil-forming processes and water-rock interactions may also yield significant information about the aqueous history of Mars, and the potential for life, past or present, on that planet. Despite extensive evidence for water on the surface of Mars, it is not clear how long water was present as a liquid. Observations of weathering products and the existence of primary minerals may provide some constraints for the presence and duration of liquid water. Therefore an understanding of weathering under Mars-like conditions may help elucidate observations from the surface of Mars. Christopher Adcock (Ph.D): Chris's research focuses on the interpretation of evidence of chemical alteration of phosphate-rich minerals on Mars. His project includes a combination of kinetic mineral dissolution experiments, field work, and modeling to better interpret observations, and the implications for the climate history and evidence of aqueous alteration on that planet.
Seth Gainey (Ph.D): Seth’s research focuses on the interpretation of transitions in clay mineral chemistry on Mars, using a combination of laboratory experiments and modeling.
Brittany Myers (MS): Brittany's MS thesis focuses on changes in Ca in arid soils as a potential biosignature.
Valerie Tu (MS): Valerie’s MS thesis focuses on the dissolution rates of amorphous Al- and Fe-phosphates under conditions relevant to Mars.
Former Students Julie Baumeister (MS): Julie's MS thesis focused on the dissolution rates of ultramafic minerals. Studying the dissolution of olivine in Lunar Crater, NV, and serpentine minerals in the Klamath Mountains, CA, helps better understand Critical Zone processes and incipient weathering of ultramafic minerals.
Jason Cornell (Independent Study): Jason's independent study examined the alteration of P-rich basalts in the Mars analog environment, Craters of the Moon, Idaho, and resulted in the following presentation: Valerie Tu (Undergraduate Research Assistant): Valerie's research project focuses on the kinetic dissolution rates of amorphous Al and Fe phosphates under conditions relevant to Mars. Mary Evert (REU) Mary’s research examined biological effects on serpentinite weathering.
