I am a structural geologist who uses field and microstructural observations to study processes occurring along active convergent plate boundaries. This work, mostly funded by the National Science Foundation, has taken my students and I to subduction zones around the world including Sumatra, Costa Rica/Panama, Alaska, Japan, Taiwan, and New Zealand. My work is multidisciplinary and has led to collaborations at Penn State that address a range of problems related to subduction such as the mass balance and active uplift rates in the forearc, the impacts of seamounts and ridges on subduction, the significance of fracture patterns and veining, and the causes for systematic cleavage patterns in collisional mountain-belts. Most recently, I have been conducting studies in Japan and Kodiak, Alaska on rocks that were deformed along the subduction interface at depths of seismogenesis to understand the processes that lead to different slip behaviors including Great Earthquakes. I also have a project with Roman DiBiase studying the impact of mountain-building processes in the active collision in Taiwan on the patterns of rock strength and how these patterns influence surface processes.
