Kynan Hughson, PhD

Assistant Professor

Geological Sciences, UAA

About

Dr. Kynan Hughson is an assistant professor in the Department of Geological Sciences at the University of Alaska Anchorage. At UAA, Dr. Hughson teaches Earth Surface Processes, Geologic Data Analysis & Visualization, Geology Seminar, and is developing a course on Planetary Geology. His research focuses on understanding the geological, geophysical, and hydrological processes that shape the surfaces of icy asteroids and worlds in our solar system.

​

Dr. Hughson obtained his B.Sc. in Geology and Physics at the University of New Brunswick and his M.S. and Ph.D. in Geophysics and Space Physics at the University of California Los Angeles. During his graduate studies at UCLA, he contributed to the geologic mapping of the dwarf planet Ceres, a multi-year effort that produced the first global map of any dwarf planet in our solar system. His research focused on the links between observable surface features on Ceres, such as landslides, impact craters, and valleys, and what they tell us about its internal structure and composition. In conjunction with other Dawn Team members, his research established that, like Earth and Mars, Ceres has abundant reserves of ground ice.

​

Dr. Hughson’s current and proposed research takes aim at better understanding periglacial geomorphology and hydrogeology of Earth, Mars, Ceres, and icy moons through a combination of observation, computer modeling, and the geophysical examination of terrestrial polar analogs. He also works on future exploration technologies for accessing the deep subsurface oceans of many icy moons, and for high-detail mapping of ground ice on Mars and Ceres. In 2020, Dr. Hughson received funding for his Pingo SubTerranean Aquifer Reconnaissance and Reconstruction (Pingo STARR) project through NASA's Planetary Science and Technology through Analog Research (PSTAR) program. Pingo STARR is a four-year (2020-2024) field campaign using geophysical methods to examine the subsurface structure of pingos.

​

Kynan lives in Anchorage with his family where they enjoy biking, skiing, backcountry camping, and board games.
