Biography
I am a trained Medical Imaging professional with a specialization in Magnetic Resonance Imaging (MRI). I am passionate about delivering precise, evidence-based diagnostic imaging. I also have a strong interest in medical research, particularly in vascular cognitive impairment, dementia, and neuroimaging.
My research focuses on the use of advanced imaging techniques, including perfusion imaging with Arterial Spin Labeling (ASL), to investigate vascular contributions to cognitive impairment and dementia, with the aim of identifying early biomarkers to inform novel and timely intervention and treatment strategies.
Projects
Under the supervision of Dr. Eric Smith, I am working on two research projects using data from the Canadian Longitudinal Study on Aging (CLSA).
The first project examines emerging evidence that COVID-19 may be neuroinvasive, with persistent neurological and cognitive symptoms such as fatigue, brain fog, and increased dementia risk—potentially driven by viral-induced coagulopathy and endothelial dysfunction contributing to cerebral ischemia, which may lead to cerebral small vessel disease . Using arterial spin labeling (ASL), this work evaluates differences in cortical grey matter cerebral blood flow between COVID-19 cases and uninfected controls, assesses MRI markers of cerebral ischemia (infarcts, microbleeds, and white matter hyperintensity volume), and examines their relationships with cognitive performance and COVID-related symptom incidence and severity.
The second project uses data from the CLSA Healthy Brain Study to identify the determinants of cerebral blood flow in the healthy general population and how these impact normal function. Both projects are funded by the Canadian Institutes of Health Research and the Weston Family Foundation.
