Dr. Chan joined the Athinoula A. Martinos Center for Biomedical Imaging at MGH in 2010 as an instructor.  Her current research focuses on imaging of cerebrovascular responses using ultrasound and MRI. She uses natural breathing/gaseous challenge to measure cerebrovascular responses in healthy subjects, patients with episodic migraine, traumatic brain injury, Huntington’s disease, atrial fibrillation and chronic fatigue syndrome.  She has developed a robust physiological model for the assessment of cerebrovascular reactivity under brief breath hold challenge.  Her model has been tested on patients to localize subtle cerebrovascular changes for disease diagnosis and monitoring of disease progression.
