Margarete A. Jadamec
NSF Postdoctoral Research Fellow, Brown University

I am currently a NSF postdoctoral fellow in the Department of Geological Sciences at Brown University. My area of research is the dynamics of tectonic plate boundaries. This includes processes at an individual plate boundary as well as the role plate margins play in regulating or responding to global mantle dynamics.

My postdoc project investigates the controls of rheology and water on velocity of the mantle in subduction zones and how that relates to the dynamics of the slab. To study this process I have constructed high-resolution 3D numerical models of the Cocos-Nazca slab gap, with a focus on the Costa Rica-Nicaragua subduction zone.
