Biography

Andrew Cyr, Research Geologist Geology, Minerals, Energy and Geophysicsjoined the USGS Geology, Minerals, Energy and Geophysics Science Center as a Mendenhall Postdoctoral Fellow and was later hired as a Research Geologist. Generally, geomorphologist interested in questions related to how climate and tectonic processes are translated into the geomorphic record approach these through field mapping of Quaternary, primarily surficial, geologic units, topographic analysis using LiDAR and Structure for Motion digital elevation data, and various applications of beryllium and aluminum cosmogenic nuclide chronologies. Most of his current work is based in California but  work in other areas as opportunity and time allows.
