About Justin Chan

I am an assistant professor of CS and ECE at Carnegie Mellon University where I direct the Semantic Signals Lab (https://semanticsignals.com/).We create scalable mobile systems for physiological intelligence using wireless sensing, signal processing, and AI.Our work falls under three broad themes:🧠 AI-driven contactless health systems: New physiological sensing systems for remote care. Intelligent mobile and wearable systems: Reimagining the sensing capabilities of everyday devices. Physics-informed acoustic perception: Sensing and interacting with the world using acoustics.We invent bio- and physics-inspired hardware systems to decode hidden signals and enable new sensory capabilities for humans and machines.Our innovations include using smartphone sensors for blood clot testing, training smart speakers to detect cardiac arrests, wireless earbuds that screen for newborn hearing loss, and detection of middle ear fluid using active sonar on smartphones and a paper cone. My work has been recognized by CACM and SIGMOBILE Research Highlights, SIGMOBILE Doctoral Dissertation Award Runner Up, and a Pervasive Computing Emerging Rockstar feature.I earned my PhD from the University of Washington and my Bachelors degree with high honors from Dartmouth.
