I am a PhD candidate in the School of Electrical and Computer Engineering at Georgia Institute of Technology. I investigate physiological biomarkers acquired using noninvasive, ubiquitous hardware to close the loop for treatment optimization and control, promoting a shift toward personalized healthcare. My work integrates a full range of applied components, such as biomedical instrumentation, signal processing, and machine learning in the context of psychological stress and heart disease to improve their measurement, understanding, and management. I primarily work in noninvasive vagal nerve stimulation for posttraumatic stress disorder.
