My research revolves around two main themes: noninvasive sensing and neuromodulation. Particularly, I work in the intersection of biomedical instrumentation, signal processing, and machine learning with a focus on mood and performance improvement. I develop noninvasive tools and signal processing algorithms in the context of psychological stress and heart disease to improve their measurement, understanding, and management. My major focus is noninvasive vagus nerve stimulation for stress-related psychiatric disorders. Application areas are cyber-physical systems (CPS), smart and connected health (SCH), Internet of Things (IoT), and novel therapeutics. [longer bio]
Starting from October 2020, I will be a postdoctoral researcher at David Geffen School of Medicine at UCLA, with Jeffrey Ardell, Kalyanam Shivkumar, Olujimi Ajijola, Marmar Vaseghi, Noel Boyle at the UCLA Neurocardiology Research Center of Excellence/Cardiac Arrhythmia Center.
