Adam Kent, Lab Director & Professor
Adam received his PhD in Geochronology and Ore Deposit geology in 1995 from the Australian National University. He has been at OSU since 2002 studying igneous and volcanic processes using ICP-MS and other techniques. He primarily works with the laser ablation ICP-MS systems and has also acted as the laboratory director since 2013. Adam also runs a research website dedicated to Mount Hood (https://mounthoodresearch.org/).
Chris J. Russo, Lab Manager
Russo received his PhD from CEOAS in 2007. His research investigated links between mid-ocean ridge basalt geochemistry and magma supply through the combined use of U-series disequilibria and trace element characterization of basalt erupted along intermediate spreading ridges. Chris returned to the Keck Collaboratory in Fall 2017.
Jennifer Fehrenbacher, Assistant Professor
Fehrenbacher’s research involves understanding and explaining changes in the Earth’s climate and oceans using geochemical data derived from microfossils (primarily Foraminifera). She also conducts experiments with live forams to understand how trace elements are incorporated into the calcite shell and to understand how future changes in ocean chemistry and temperature will affect their ability to calcify.

Brian Haley, Associate Professor
Haley studies trace metals for environmental and climate change studies, with special focus on rare earth elements and neodymium isotopes.
Jessica Miller, Associate Professor
Miller uses trace metal composition of shells, bone, cartilage, and otoliths (fish ear stones) to learn about larval dispersal and mixing and movement in marine organisms. She also uses strontium isotopes (87Sr:86Sr) to determine natal origins and migration history in anadromous fishes, such as Chinook salmon.
Julie Pett-Ridge, Associate Professor
Pett-Ridge uses trace metals and isotopes (including Mo, Nd, Sr, U-series) to study geochemical, hydrologic, and biogeochemcial processes in the critical zone.
Alyssa Shiel, Assistant Professor
Shiel studies the biogeochemical cycling of metals and anthropogenic activities as metal sources to the environment using a variety of geochemical tools. More detail on her research can be found at http://blogs.oregonstate.edu/shiellab/.
Marta Torres, Professor
Torres applies state-of-the-art inorganic elemental and isotopic measurements of fluids and authigenic minerals to understand drivers and consequences of fluid transport along plate boundaries. Applications of these geochemical tracers range from centimeter-scale heterogeneity at cold seeps to hydrologic changes that span several kilometers along subduction zones; and target questions from the microbial processes to earthquake generation.
Andy Ungerer, Lab Manager Emeritus
After 30+ years working in Geochemical analysis, long time laboratory manager Andy Ungerer retired in 2017, although he still comes in to help out as an advisor.
