The GeoSPACE project is a collaborative project that brings together a rotating team with expertise in planetary science, volcanology, field geology, geoscience education, accessibility and technology. Our roster of guest instructors has not yet been finalized for 2026, but we always have a roster of gifted scientists and educators participating in the course. Stay tuned for updates early in the spring semester!
Anita Marshall (She/her) is a Senior Lecturer at the University of Florida, Gainesville.
My primary research area is Geoscience Education, specifically academic and social engagement in field courses, how to form belonging and community in educational spaces, and the barriers to participation for people with disabilities in science disciplines. My secondary research area is volcanology, where I utilizes near-surface geophysics to examine tephra deposits and sub-surface features of small-volume volcanic eruptions. I'm passionate about geo-ethics and culturally respectful and sustainable field work. I am a member of the Choctaw Nation of Oklahoma and have a physical disability and chronic fatigue. I am so excited to get out in the field (in person or remote) with our GeoSPACE students and show them the volcanoes I fell in love with as a student, and how anyone can do field work if provided the proper tools and support.
Lis Gallant (she/ella) is an assistant professor and volcanologist at the University of Hawai'i Hilo.
My primary area of research is volcanology, specifically lava flow hazards and eruption response. I work with the Hawaiian Volcano Observatory to conduct same-day geochemical analysis or eruptive products and assist with equipment deployment during eruptions. My personal research combines physical field work with geophysical data collection to understand how volcanoes grow and how lava flows behave.
David A. Williams (he/him) is a Research Professor in the School of Earth and Space Exploration at Arizona State University, Tempe, Arizona. Dave will be joining us for the first week of the field course.
I'm the Director of the Ronald Greeley Center for Planetary Studies, a NASA-funded planetary data center at ASU, and also the Director of the NASA Planetary Aeolian Laboratory, which administers wind tunnels the Ames Research Center in California. I'm currently performing research in volcanology and planetary geology, with a focus on planetary mapping, geochemical, and remote sensing studies. My current research focuses on planetary geologic mapping of bodies across the Solar System, and computer modeling of the physical and geochemical evolution of lava flows in a variety of planetary environments. I was involved with NASA’s Magellan Mission to Venus, Galileo Mission to Jupiter, Dawn Mission to asteroid Vesta and dwarf planet Ceres, and ESA’s Mars Express orbiter mission. I'm a member of the Janus camera team for the ESA JUICE mission, and the Deputy Imager Lead and a Co-Investigator on NASA’s Psyche Mission. In 2014 I was elected a Fellow of the Geological Society of America, and asteroid 10,461 DAWILLIAMS was named after me.
Alex Bearden (he/him) is a volcanology graduate student at UC Berkeley in the Department of Earth and Planetary Science.
JJ Ruse (he/him) is a 2025 graduate of the University of Florida who will soon be starting graduate studies in planetary geology at the University of Georgia.
All of these people have been involved with the GeoSPACE program and many continue to rotate in and out as part of the teaching team each year. We also have a number of guest professionals not listed that join us for a field day through out the course.
Sean Thatcher, is a Lecturer in the Engineering and Environmental Science Department and the Earth and Ocean Science Program Coordinator at CUNY College of Staten Island. Sean's research focuses on environmental geoscience, GIS and accessible science.
Jen Piatek (She/her) is a professor of planetary geology and chair of the Geological Sciences department at Central Connecticut State University. Jen's research involves remote sensing of planetary surfaces.
Steve Elardo (he/him) is an Assistant Professor and NASA Early Career Fellow at the University of Florida. Steve's work uses high-pressure and -temperature experiments, studies of planetary samples, and non-traditional stable isotope geochemistry to study planetary evolution.
Amy Williams (she/her) is an Assistant Professor and NASA researcher at the University of Florida. Amy's primary research area is astrobiology/ geobiology; exploring how life is preserved in the rock record as a biosignature, and how we can detect those biosignatures both in ancient rocks on Earth and Mars.
Trevor Collins (He/him) is Senior Research Fellow in Technology-Enhanced Learning at The Open University (UK).
McKayla Meier (She/Her) is a PhD student at the University of Florida studying planetary volcanism and geochemistry. McKayla co-developed the virtual program.
Yesenia Arroyo (they/them) is an early career researcher at NASA Goddard with the Habitable Worlds program.
Anna Baker (she/they) is a PhD candidate at Northern Arizona university in the Astronomy and Planetary Science Department.
