I am an Assistant Professor in the Department of Geological Sciences. I obtained my B.Sc. in Geology and Physics at the University of New Brunswick with a focus on impact cratering and shock metamorphism. I earned my M.S. and Ph.D. in Geophysics and Space Physics at the University of California Los Angeles. As an associate member of NASA's Dawn mission science team, I contributed to the geomorphologic mapping of the dwarf planet Ceres. My planetary research focuses on the links between the morphology of surface features on Ceres, such as landslides, impact craters, and hills, and what they tell us about its internal structure and composition. In conjunction with the Dawn Science Team, my work established that, like Earth and Mars, Ceres has abundant reserves of ground ice. 
I also work on understanding the geological, geophysical, and hydrological processes that shape the surfaces of planets and icy asteroids. On Earth, I study the shape and structure of periglacial landforms such as pingos and rock glaciers and use geophysical methods to link their forms to their subsurface cryohydrologic structure. I am the lead investigator for the Pingo SubTerranean Aquifer Reconnaissance and Reconstruction (Pingo STARR) project. This NASA sponsored PSTAR program is currently collecting a large quantity of high-fidelity geoelectrical and ground penetrating radar data over a series of pingos in the North American Arctic. Pingo STARR is a collaboration between researchers at the University of Alaska Anchorage, Georgia Tech, the Colorado School of Mines, the Planetary Science Institute, and the University of Toronto.

Research Interests

I am fundamentally interested in how the shapes of landforms inform us of their formation, internal structure, and composition. I am particularly interested in how groundwater and ground ice are distributed and structured in glacial and periglacial environments and what landforms they create on Earth and in the cryospheres of other worlds in our solar system. I use a combination of remote sensing, geophysical field methods, and geophysical modeling to better understand the cryostratigraphic structure of features permafrost and periglacial landforms on Earth and infer the implications for potential analog habitats on Mars, Ceres, and other icy-rich worlds.
My current Pingo STARR project uses a combination of remote sensing, ground penetrating radar, electrical resistivity tomography, and transient electromagnetic sounding to probe the 3D structure of pingos in the North American Arctic. The goals of this project is to thoroughly characterize the subsurface structure of active pingo systems during their most frozen periods, test the synergies of various geophysical methods in a planetary analog environment, and to inform the ground ice surveying strategy for next generation of planetary missions.
