Biography and Research Abstract
I recently received my Ph.D. in Biomedical Engineering from Texas A&M University under the supervision of Dr. Roozbeh Jafari. My research lies at the intersection of machine learning, signal processing, algorithm design, and embedded and wearable systems to improve medical care and enhance lives. In my Ph.D. dissertation titled “Wearable Sensors for Precision Medicine through Personalized, Holistic, and Context-Aware Analytics”, I mainly focused on analyzing wearable and IoT sensors data to extract actionable physiological and behavioral information.
As an interdisciplinary researcher, I build machine learning algorithms and wearable and embedded systems to enable remote health monitoring and precision medicine in day-to-day life. Recently, a growing percentage of healthcare takes place outside the traditional walls of clinical care and is tightly coupled with daily experiences. Although the field of remote and decentralized patient care and precision medicine, catalyzed by the COVID-19 pandemic, does not replace medical care, it can complement that by providing important insight into the onset of disorders and the effectiveness of therapeutics, and that is the mission of my research. I recently lead a team of graduate researchers in a large-scale collaborative project on infection prediction through physiological monitoring with common-off-the-shelf wearables to address the COVID-19 pandemic.
