I am interested in the structural and volcanological aspects of extensional tectonics, with special focus on the brittle portion of the crust. I’m invested in research such as uncovering paleostress histories of continental rifts, brittle tectonics and dynamics of oceanic spreading centers, and rheology of basaltic lava flows.

In the summer of 2016, I completed a field season mapping structural data in southern Iceland near the intersection of two plate boundaries: the South Iceland Seismic Zone and the Eastern Volcanic zone. The goal of this project was to characterize faulting and diking patterns to test a dynamic hypothesis related to oceanic rift propagation and microplate kinematics. Data from this region show that strain related to propagation of the Eastern Volcanic zone is being accommodated by massive rift-parallel strike-slip faults.

Through the SU Lava Project (http://lavaproject.syr.edu/), I have begun to study the rheology of basaltic lava flows using photogrammetric 3D modelling. I am using 3D models and Fourier analysis to quantify complex fold geometries on pahoehoe lava surfaces. The goal is to understand the connection between lava crustal rheology and physical properties of the basalt. These analyses will also be used to compare lava from Iceland with lava made at SU.
