Ellyn Huggins (B.Sc., UC Davis 2017)
(she/her/hers)
Ellyn's dissertation combines thermodynamic models, melt inclusion work, and other petrologic and mineral scale constraints to understand magma transport and the textural evolution of magmas prior to eruption. Her focus is on volcanoes of the Alaskan Peninsula.
In addition, Ellyn has sea-going experience participating in cruises to the South Atlantic and the off-shore region of the Alaskan Peninsula.

Shasta Longo (B.Sc., Montana State 2021)
(she/her/hers)
Shasta joined us for a MSc project focussed on the Great Basin and igneous processes. Shasta is conducting a USGS/EDMAP mapping project of the exposed Eocene magmatic system at Swales Mountain, NV. Her MS work uses this mapping effort combined with petrologic and geochemical analyses of the igneous rocks and their mineral phases to develop a model for the assembly of this magmatic system that is tightly spatially and geologically associated with Carlin-type gold deposits.

Jakob Scheel (M.Sc., Hamburg, Germany, 2022)
(he/him/his)
Jakob has join the group after completing an MS degree in geophysics. In his dissertation he combines multi-phase fluid dynamics models to study the formation and destruction of mafic enclaves (in UNR collaboration with colleague Dr. M. Gardner) with field studies on mafic enclaves from the Chaos Crags in Lassen Volcanic National Park.

Andrea Buian (M.Sc., Florence, Italy, 2021)
(he/him/his)
Andrea's doctoral work focuses on the McDermitt Caldera and the volatile pathways that occurred in pre-caldera, caldera, and post-caldera eruptive products. The McDermitt Caldera and its magmas has produced one of the largest Li deposits (Li-clays in lake sediments) in the world. His work will provide constraints on the magmatic-hydrothermal evolution of the McDermitt caldera through time and the Li enrichment processes.
This project is in collaboration with former NBMG colleague M. Harlaux.

Audrey Topp (UNR undergraduate)
Has worked on two projects to study the tephra deposits of the 2011-12 Puyehue Cordon Caulle eruption. She is looking at syn-depositional deformation as well as grain size studies of the tephra; the latter in collaboration with colleague Dr. Thomas Giachetti from the University of Oregon.

Pablo Salas (Ph.D. 2020, Outside group member, University of Concepción, Chile)
Pablo's interests lie at the intersection of volcanology and ore deposits. Following several years in the industry, he recently earned his Ph.D. working on the eruptive history and magmatic processes at Los Hornitos cinder cones, Chile. This magmatic center is among the most primitive in the Southern Andean Volcanic Zone, representing a unique opportunity to explore magma transport and deeper crustal processes.

Curtis Johnson (Ph.D., UNR 2020)
Curtis is an expert on precious metal mineralization in the Great Basin. His thesis focused on a regional transect across basin to explore how the crust influences the geochemical pathways of magmas and fluids. He used detailed age dating combined with trace element chemistry and speciation on accessory phases on gold- and copper-related magmatic intrusions. (Advisors: Mike Ressel and Philipp Ruprecht)
