Gulnaz Begum, PhD

Assistant Professor of Neurology

Biographical Sketch

Dr. Begum’s research is aimed to provide an in-depth molecular understanding of the role of astrocytes in neurogenerative diseases (Stroke, Traumatic brain injury, and Alzheimer’s disease).  Her lab investigates the molecular signals/mechanisms that lead to reactive astrocyte phenotype and how reactive astrocytes modulate the normal astrocyte-neuron, and astrocyte-vasculature interactions in brain disorders. Mouse genetics, multi-omics, fluorescence ion imaging, and tissue culture techniques are some of the multifaceted experimental approaches used in her lab to probe the function of reactive astrocytes in normal and diseased brain. Using the insights from these studies, she aims to ultimately transform astrocytes from “toxic” to “protective” state as a therapeutic strategy. Dr. Begum has received funding from NIH/National Institute of Neurological Disorders and Stroke (NINDS) and has over 27 publications.
