Short Description: Network detection and definition in fMRI networks


My work in the Petersen lab is concerned with the detection and description of brain networks in MRI data. Resting-state functional connectivity MRI (and many other methods) can be used to construct networks representing anatomical or functional relationships between brain regions, but once constructed, these networks are often large, information-dense, and difficult to describe, or even understand. My research approaches these networks mathematically, and in large part is concerned with reducing the apparent complexity of the networks by defining communities within the networks. We initially applied these approaches to specific brain networks, such as the "control" or "default" networks, and have since extended these analyses to a wide variety of brain networks.
