Gabriel Ferragut grew up in Fargo, ND and graduated in 2017 from North Dakota State University with B.S.’s in Physics and Geology. His undergraduate research ranged from the application of optically stimulated luminescence dating on Mars to paleoclimate reconstruction in the Great Basin of North America through hydrologic mass balance modeling, but more recently an IRIS internship has shifted his focus to seismology. Before starting at UO he was working at the USGS Menlo Park investigating Sn velocities and the implications for mantle temperature beneath Saudi Arabia. At UO, Gabe will be joining Doug Toomey’s seismology group and hopes to explore crustal and mantle structure of plate boundaries in the PNW through tomographic imaging as well natural hazard analysis and early warning utilizing the so called Internet of (Wild) Things (IoWt.)  In his spare time Gabe very much enjoys cooking, backpacking, and, true to form as an Earth scientist, has a healthy respect for, and interest in, the brewing and drinking of beer. His chief obsessions outside of the academic setting, however, are fly fishing and fly tying, which as you might be aware, are without a doubt the greatest non-scientific activities ever conceived by humans.
