Dr. Sierra (Wiegman) Brown holds a B.S. (2016) in Geophysics and Geochemistry from SUNY Fredonia, and M.S. (2018) and Ph.D. (2022) degrees in Earth, Environmental, and Planetary Sciences from Brown University. Brown is also an enrolled member of the Shinnecock Nation, and draws on the practice of “Two-Eyed Seeing” to provide unique insights that integrate indigenous and western approaches to knowledge.

Recent Postdoctoral Research Fellow Kai-Xun Chen has published a new paper in Geophysical Research Letters, titled “Seismic evidence for a mid-lithospheric discontinuity in 155 million-year-old Pacific lithosphere. Consistent with now-frozen melt that was trapped in the young lithosphere close to the ridge.” The publication lays out evidence for a low velocity layer inside old oceanic lithosphere. Dr. Chen completed this research while he was a postdoctoral researcher in DEEPS, working with Prof. Don Forsyth and Prof. Karen Fischer.

DEEPS PhD candidate César Bucheli recently published a new paper in Contributions to Mineralogy and Petrology, titled “What can we learn from geothermobarometry at the dacitic Doña Juana Volcanic Complex (Colombia)? Implications for understanding Pleistocene crystal mushes and pre-eruptive storage conditions in the Northern Andes.” Bucheli and co-authors reconstructed the geochemical behavior of Pleistocene melts feeding eruptions of the Doña Juana Volcanic Complex (SW Colombia, Northern Andes) and found evidence to suggest the existence of one of the first examples of long-lived trans-crustal magma systems in the country.
