Anna G Orr serves as Nan and Stephen Swid Assistant Professor of Frontotemporal Dementia Research and Assistant Professor of Neuroscience at Weill Cornell Medical College's Brain and Mind Research Institute since 2016, leading pioneering research on astrocyte biology in dementia pathogenesis. Her educational background includes: Ph.D. from Emory University (2008) B.S. from Allegheny College (2002) Dr. Orr's research program centers on astrocytic-neuronal interactions , mitochondrial signaling , and neuroimmune mechanisms through three interconnected pathways: neuroimmune , oxidative , and G protein-coupled signaling . Her lab investigates how these mechanisms influence neuroinflammation, protein aggregation, synaptic function, and behavioral outcomes in dementia, with parallel therapeutic discovery efforts targeting astrocytic pathways for novel dementia treatments. Analysis of her 15 most recent publications (2025-2010) reveals escalating focus on astrocyte-specific dementia mechanisms , particularly mitochondrial ROS signaling, sex-dimorphic memory effects, TDP-43 pathology interactions with antiviral pathways, and lipid dysregulation in neurodegeneration. Her work consistently bridges molecular discoveries with therapeutic applications, demonstrating increasing NIH funding support for translational approaches. Key scientific recognitions include: NIH K99/R00 Pathway to Independence Award (2017) Leon Levy Fellowship in Neuroscience (2021) Nan and Stephen Swid Endowed Professorship (2021) Outstanding Neuroscience Teaching Award (2021) Dr. Orr actively mentors eight trainees across career stages, including Ph.D. candidates Evelyn Hardin and Constance Zhou, while securing major NIH grants as Principal Investigator for projects like Uncovering Dementia-Related Lipid Alterations in Astrocytes (NIA 2024-2026) and Mitochondrial Complex III Free Radicals in Dementia Pathology (NIA 2020-2026), alongside collaborative awards from the Alzheimer's Association. Her Orr Lab maintains a dual focus on mechanistic astrocyte biology and therapeutic translation, with current projects examining astrocytic TDP-43 dysregulation, mitochondrial complex III signaling, and sex-specific memory mechanisms using advanced in vivo techniques and disease models.
