Tarek Hamid

PhD Candidate, University of Virginia

I am a PhD candidate at the University of Virginia, advised by Professor Amanda Watson. Before starting my PhD, I held multiple roles at companies such as Johnson & Johnson, Sotera Digital Health, JPMorgan Chase, and the DoD. I received my Masters in Biomedical Engineering from Johns Hopkins University and my Bachelors in Biomedical Engineering from The College of New Jersey.

I believe that everyone deserves to live a happy and healthy life in the pursuit of their goals and dreams. That belief drives my research: if we can make health monitoring more accurate and accessible, we can give people the tools to take care of themselves and the people they love. To this end, the main focus of my research has been utilizing broad-spectrum PPG and machine learning/signal processing techniques to detect new biomarkers using wearable sensors.

Using broad-spectrum PPG, we are currently working on uncovering new biomarkers such as skin-tone and glucose.
Broad spectrum sensing exploits differential wavelength penetration to disentangle physiological signals from noise.

Outside of research, I enjoy playing basketball, lifting, baking, and cooking. I am also passionate about mentorship and volunteering.
