Ellen Metzger

Ellen Metzger
Professor / BAESI Director

I am a metamorphic petrologist and science educator with a wide variety of interests.  My current research focuses on high-grade metamorphism in the Adirondack Mountains of New York, Miocene volcanics in the Central California Coast Ranges that formed  in a subduction-transform transitional setting, and education for sustainability.

Bob Miller in the field

Robert Miller

I am a field-oriented structural geologist and tectonicist. My research focuses on the tectonic evolution of the North Cascades of Washington and British Columbia, and the construction, emplacement, and structure of granitic plutons in the Cascades and Sierra Nevada. Major current projects are on relationships between magmatic flare-ups, crustal structure, and arc rheology, and on displacement histories of Mesozoic and early Cenozoic strike-slip fault zones in the Pacific NW

Carlie Pietsch

Carlie Pietsch
Assistant Professor

I am a deep-time marine biologist (paleontologist) working with an active group of undergraduate and graduate students to study ancient mass extinction and extreme climate events using marine fossils (snails, plankton, sea urchins, etc.), the surrounding sediments, and chemical signals preserved in fossilized shell.

Ryan Portner

Ryan Portner
Assistant Professor

I am a volcanologist that uses sedimentology/stratigraphy, igneous petrology, geochemistry, geochronology and field mapping to study oceanic crust formation, submarine eruption dynamics and volcaniclastic transport/deposition processes on the seafloor. To do this my research team and I integrate field studies of modern and ancient deposits exposed on the seafloor and on land with laboratory based analytical approaches.
