My research is focused on understanding the evolution of Mediterranean-style subduction zones with constraints from exhumed subduction complexes at the Betic Cordillera (Southern Spain) and Sikinos and Ios islands (Cyclades, Greece). My approach is to integrate a suite of geochronologic and geochemical analyses on zircon, apatite, and rutile, including U-Pb and trace elements split-stream analyses as well as 2D elemental mapping techniques.
The ultimate goal of my research is to (1) set constraints on the paleogeographic position of the different units within the Internal Betics and the spatial relationship between them,
(2) determine initial stratigraphic architectures and examine how the rocks were subsequently deformed during subduction/exhumation (coherent vs. incoherent packages), and
(3) investigate the geologic conditions during metamorphic growth of zircon grains, to better understand the timing, style, and degree of metamorphism.

During my Masters I investigated the tectonometamorphic evolution of Sikinos and Ios islands in Cyclades Greece.I tried to determine the pre-subduction stratigraphy, paleogeography, and find the evidence for structural repetition and juxtaposition, by differentiating between deposition, and subduction zone processes. I used zircon U-Pb geochronologic techniques integrated with structural geology and geologic mapping.

For my undergraduate research I worked on Andros Island in Cyclades Greece, I performed geologic mapping and collected samples for microstructural analyses. I differentiated the foliation generations in blueschist and greenschist rocks and set relevant time constraints.
