I am biosensor research scientist at Reality Labs at Meta. Previously I was a postdoctoral researcher at David Geffen School of Medicine at UCLA, with Jeffrey Ardell at the UCLA Neurocardiology Research Center of Excellence. I finished my Ph.D. in December 2020 in the School of Electrical and Computer Engineering at Georgia Tech. I worked with Omer T. Inan and I was a member of the Inan Research Lab.
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 to improve their measurement, understanding, and management. My major focus is noninvasive vagus nerve stimulation for stress-related psychiatric disorders. Application areas are Internet of Things (IoT), cyber-physical systems (CPS), smart and connected health (SCH), and novel therapeutics. [longer bio]
