Dr. Alex Morgan is a geologist who uses spacecraft data, computer modeling, and field work to decipher the environmental conditions present during the evolution of planetary landscapes. He is primarily focused on the geologic history of the martian surface - Mars today is a cold, dry, global desert, but ancient river valleys, lakebeds, and deltas indicate that is was once a much warmer and wetter world. Alex also studies desert regions of Earth, with a particular focus on alluvial fans. He received his B.S. from the University of California, Santa Cruz in 2010, and worked at NASA Ames Research Center for a year before moving to the University of Virginia, where he earned his Ph.D. in 2018.
