Eirini Poulaki

Research Interest

I am a structural petrochronologist studying tectonic processes by using the metamorphic rock record. Using a wide range of field- and lab-based techniques, including geochronologic and geochemical analyses, field mapping, (micro)structural observations, thermodynamic modeling, oxygen isotopic analyses, and SEM (EBSD/EDS) analyses, Eirini’s research is centered around the understanding of the nature of the fluid-rock interactions and the metamorphic and structural behavior of the lithosphere. 

Most specifically, I have projects on (1) the nature of deformation and fluid rock interactions along the subduction interface, which has implications for understanding modern subduction zone processes, including hazards; and (2) constraining the pathways and influence of fluids during mantle exhumation, including serpentinization, which controls strain localization in the lithosphere and has implications for deep-sea hydrothermal circulation.

Opportunities

I am seeking two students to join the MO.S.A.I.C. research group (Metamorphism, Structure, and Isotope Chronology) for two different projects:

One project will focus on reconciling the geophysical observations of slow slip and tremor with geologic and rheological constraints. The project will involve a significant component of fieldwork in the Franciscan, California, (and if desired by the student in the Cyclades, Greece), geochronology/geochemistry, metamorphic petrology, and structural work.

The second project will focus on the feedback between deformation and fluid/rock interactions during mantle exhumation. This project will utilize existing samples collected during IODP Expedition 402 in the Tyrrhenian Sea. The project will involve geochronology/geochemistry, microstructural work, and stable isotope analyses.
