June completed her bachelors degree at Illinois State University in Normal, IL, in 2003. She spent the first half of the summer of 2003 running seismic lines for the Illinois State Geological Survey before starting her PhD studies at the University of Idaho in the Fall of 2003. June is investigating the surface characteristics of Arabia Terra in the equatorial western hemisphere of Mars, mapping out evidence of past water concentrations on Mars using epithermal neutron data from the Mars Odyssey spacecraft (used to determine water-equivalent hydrogen concentrations, or WEH) as well as surface evidence of ancient drainages. She is also examining the characteristics of normal faulting in the region and how structurally controlled on topography may have ultimately impacted on WEH concentrations. June is aiming to complete her PhD degree in the Summer of 2009.

Jon received a BA in physics from Wheaton College in Massachusetts in May 2008. He became interested in planetary geology by spending two of his undergraduate summers researching craters on Ganymede and doing morphological mapping of Chasma Boreale, Mars. Jon's current work takes him back to the Jupiter neighborhood, where he is developing a detailed map of young fractures on the moon Europa. The fractures will be analyzed in the context of tidal stress fields to determine if there is any evidence for active tectonics on this icy moon. Jon is aiming to complete his MS degree in the summer of 2010.

Alex received his bachelors degree in physics from Virginia Tech in 2003. He received a bachelors and a masters degree in geology from West Virginia University in 2006 and 2008, respectively. His MS research explored the crustal thinning off the northwest coast of Alaska beneath the Herald Arch and Hope Basin. Alex worked as a field assistant in the Bendeleben Mountains, Alaska in the summer of 2006. While completing his MS degree, he worked as an exploration geologist specializing in coalbed methane with a company based in central West Virginia. Alex is a PhD student in planetary geomechanics, studying the fracturing of ice in the south-polar region of Saturn's moon Enceladus to establish the stress history recorded in the fracture sequence and provide insights into the eruptive plumes emanating from cracks in this region.

Sandi completed her M.S. degree in geophysics at the University of Idaho in December 2004. Her research was aimed at estimating the thickness of the brittle or elastic portion of the ice shell of Jupiter's moon, Europa. She also examined evidence for potential large-scale impact features on Europa that may have led to the development of a type of feature called chaos. The results of her research were published in the October 2005 volume of the journal Icarus (Special Volume on Europa's Icy Shell). Sandi is currently living in Moscow, Idaho, as a private consultant. She previously served on the board of directors for the Pacific section of the American Astronomical Union.

Thesis: Surface monocline development above normal faults in basalt: numerical models and observations from southwest Iceland. Papers: In preparation.

Nate completed his M.S. degree in geology at the University of Idaho in September 2006. His research focused on the relationship between normal faulting and surface folding in southwest Iceland. He developed a conceptual and numerical model to explain the evolution of a monocline above an active subsurface fault and determined a mechanism for inferring subsurface fault geometry and evolution based on spatially variable monocline characteristics. The results of his research will soon be submitted to the Journal of Structural Geology. Nate is currently based out of Houston, Texas, but is temporarily assigned to Denver, Colorado, working as a geologist for the Hess Corporation, an energy resource company.

Thesis: The magmatic influence on temporal strain partitioning at an oblique spreading center, southwest Iceland. Papers: In preparation.

Leslie completed his M.S. degree in geology at the University of Idaho in December 2005. His research examined evidence for temporal strain partitioning on the Reykjanes Peninsula, Iceland, through a detailed mapping survey and analysis of faulting and fracturing patterns in this oblique spreading environment. He performed an exhaustive search for clues in the fracture history to indicate the importance of the magmatic cycle on the structural architecture of the region. The results of his research will soon be submitted to the Journal of Structural Geology. Leslie is currently living in Rutland, Vermont, where he has divided his time between working as a river scientist for the state of Vermont at the Department of Environmental Conservation, teaching introductory courses at Castleton College, and working as a ski patroller during the winter months.

Julie completed her M.S. degree in geology at the University of Idaho in August 2006. Her research examined the growth of curved cycloidal cracks on Jupiter's moon, Europa. She utilized mathematical models based on linear elastic fracture mechanics in tandem with calculated tidal stress states in Europa's ice shell to develop a mechanical model for the development of cycloid cusps in a manner analogous to shearing-induced tailcracks along strike-slip faults. She thus showed that shearing deformation is a major aspect of the tectonics on Europa. Julie is currently living in Michigan where she works as an environmental geologist for GZA GeoEnvironmental Inc., in Livonia, MI.
