Connor Phipps

Connor Phipps

Connor is a Graduate Research Assistant in the lab. He is also in the Interdisciplinary Graduate Program in Biomedical Sciences and studies the intrinsic functional networks of the brain utilizing a connectomics perspective. Specifically, he is interested in analyzing the properties of the intrinsic functional networks of the brain through graph theoretical measures to better understand the interactions between functionally connected units of the brain. His research goal is to apply noninvasive neurostimulation and connectomics to remediate memory in memory-impaired populations such as those affected by Alzheimer’s disease.
