Biography and Education


Emory University, BS Neuroscience and Behavioral Biology 2016 I conducted my undergraduate thesis under Hillary Rodman, studying aberrant prefrontal cortex GABAergic circuitry in Rhesus macaque following hippocampal injury. After graduating, I worked in Donna Maney's Bird Brain lab studying neuroendocrine pathways in two species of songbirds: White Throated sparrows and Zebra Finch. After joining the MD/PhD program at UKCOM I worked with Dr. Sharon Walsh investigating behavioral change among those suffering from substance use disorders and endocarditis. Currently, I work in Brian Gold's Cognitive Neuroscience of Aging laboratory investigating neuroimaging biomarkers of aging.


Current Year: G4


I am particularly interested in validating neuroimaging biomarkers of aging and dementia that can be used to identify at risk patients and screen for therapeutic efficacy. My current project focuses on enlarged perivascular spaces which is a commonly seen lesion on brain scans of elderly individuals and a validated marker of cerebral small vessel disease. Cerebral small vessel disease is a major risk factor for certain forms of dementia but little work has explored the usefulness of enlarged perivascular spaces as a predictive biomarker of dementia symptoms.

Dissertation title: Investigating enlarged perivascular spaces as a neuroimaging biomarker of cerebral small vessel disease.
