Christian Klimczak is Assistant Professor of structural geology in the Department of Geology at the University of Georgia. He is an expert in rock and fracture mechanics applied to deformation properties of rock and lithospheres, as well as fault mechanics on Earth and other terrestrial planetary bodies, with approaches taken from field work, remote sensing, and modelling. Geoffrey Collins is a Professor at Wheaton College and a planetary scientist using the tools of geology, geophysics, and remote sensing to learn about the other planets in our solar system. He is primarily interested in geological processes on the icy satellites of the outer solar system, and he has been involved with various NASA projects such as the Galileo mission to Jupiter and the Cassini mission to Saturn. He has also spent time researching geological processes on Europa, Enceladus, Dione, Titan, Venus, Triton, and Pluto, among others. He teaches a diverse set of courses, including Geology, The Solar System, Remote Sensing, Astrobiology, and Geophysics. Paul Byrne is a planetary geologist with expertise in the study of tectonic and volcanic systems on silicate planets and icy moons, and Assistant Professor of structural and planetary geology in the Department of Marine, Earth, and Atmospheric Sciences at North Carolina State University. He has published on physical volcanology, tectonism, and volcanotectonic deformation on Mercury, Mars, Earth, the Moon, and the icy moons of Saturn.
