I run the 4-D topography lab in Boulder. I'm a fellow of the Cooperative Institute for Research in Environmental Sciences (CIRES) and am rostered in Geological Sciences.

Mike MacFerrin is a post-doctoral research associate in the Earth Science and Observation Center (ESOC) within the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado in Boulder. Dr. MacFerrin's specialties focus on the interactions of increased meltwater on snow and firn properties on the Greenland ice sheet, with a secondary specialty in using Computer Vision and Machine Learning technologies to extract information from satellite and airborne remote sensing observations.

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.

Jasmine is a fourth year PhD student working in the polar regions on the interactions between ice mass changes and the underlying crust and mantle. She utilizes digital elevation model time-series data, derived from optical remote sensing satellites, combined with ground and satellite geophysical methods such as GPS, InSAR and GRACE.
