Ryan Cassotto is a Postdoctoral Researcher in the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado. His research interests are in the geophysical deformation of the shallow earth, with a particular focus on tidewater glaciers. He utilizes a variety of remotely sensed and field-based observations to facilitate his research and has completed four field seasons in Greenland and three in Alaska. Ryan earned a PhD in Earth and Environmental Sciences from the University of New Hampshire in 2017. His dissertation work focused on the use of terrestrial radar interferometers to monitor dynamic changes along tidewater glacier termini due to variations in ice mélange (an agglomeration of iceberg clasts and sea ice in many proglacial fjords), iceberg calving, ocean tides, and precipitation. Ryan received a Master of Science in earth science from the University of New Hampshire in 2011. His thesis analyzed the interannual variability of winter ice mélange derived from satellite-based thermal infrared observations. Prior to his work in earth science, Ryan earned a bachelor’s degree in electronic engineering technology from the University of Hartford and spent 9 years as an Electromagnetic Compatibility Engineer in the defense and high-tech sectors.
