Tectonoclimatic Evolution of the Forearc of Southern Peru
Funding: Rothschild Advanced Student Work Grant (College of the Atlantic), Davis International Travel Award (College of the Atlantic)
Collaborators: Sarah R Hall (College of the Atlantic), Carlos Benavente (INGEMMET, Peru), Gemma Venuti (College of the Atlantic) Project description: For my undergraduate thesis, I worked with Dr. Sarah Hall at College of the Atlantic on adding constraints to the recent tectonoclimatic record of the forearc of Southern Peru. We used a combination of microstructural, field and remote landscape analysis methods to characterize the timing and coupling between earthquakes an ENSO events and its effect on the recent evolution of the landscape of the Atacama Desert.

Structural Controls of Seismicity in Western Quebec, Canada
Mentors: Yajing Liu (McGill University), Rebecca Harrington (McGill University), John Onwuemeka (McGill University), Sarah R Hall (College of the Atlantic), Sam Roy (University of Maine)
Project description: For my summer internship at the McGill University Seismology Lab, I worked on constraining the source parameters, focal mechanism solutions, and b-value distribution of events in the Western Quebec Seismic Zone. The following semester, I worked on landscape fabric and drainage analyses to couple the seismic data with geological structures.

Interplay between Structural and Glacial Processes in Acadia National Park
Collaborators: Sarah R Hall (College of the Atlantic), Gemma Venuti (NOAA)
Project description: We compared the orientation of fractures, linear features, and glacial landforms in Acadia National Park to determine the relationship between glacial features and pre-existing structures. We measured fractures and glacial features at multiple scales by combining field measurements with remote landscape analysis in GIS. We found the location and extent of glacial landforms is controlled by the pre-existing tectonic fabric, where different joint sets determine where glaciers are able to abrade and pluck. Presentations: Poster presentation at the Northeastern GSA Annual Meeting 2016. Outstanding poster award winner. Abstract here. |
