Profiles in "Geological Processes" Expertise Area

  • Barton is a complex systems scientist who combines anthropology, archaeology, earth science, and information technologies to study long-term dynamics and interactions of people and landscapes in the Anthropocene.
  • Heimsath researches how the earth's surface changes under the influence of climate, tectonic and human forcing. He runs a geochemistry lab to quantify surface processes and teaches undergraduate and graduate students.
  • Christensen uses spectroscopy, radiometry, field observations, numerical modeling, and builds flight instruments to study the geology and history of planets and moons.
  • Steven Semken is an ethnogeologist and geoscience education researcher whose trans-disciplinary work explores ways that sense of place and cultural knowledge influence teaching, learning, and research in the Earth sciences.
  • Williams' research focuses on the chemical composition of clays and their interactions with organics and microbes.
  • Sharp teaches mineralogy, field geology, and electron microscopy. His research interests include impacts and shock metamorphism in meteorites, high-pressure minerals and phase transformations in Earth's mantle.
  • Srinidhi Ravi is a 5th year PhD candidate under Dr. Mark Robinson on the Lunar Reconnaissance Orbiter Camera (LROC) team. Her research focuses on constraining the lithospheric evolution of the lunar Procellarum KREEP Terrane.
  • Julia Johnson is a geologist and geoscience-education researcher. Her geologic research focuses on the geology of Arizona, and her education research involves the use of concept sketches in geoscience learning and teaching.
  • Burt is professor in the School of Earth and Space Exploration and an economic geologist with experience in mineralogy, petrology, and geochemistry.
  • James Tyburczy is a mineral physicist studying the physical and chemical properties of minerals, melts, and rocks. He also studies environmental geophysics, effects of shock and implications for early planetary evolution.
