My lab is hiring a postdoc!
The Semantic Signals Lab at Carnegie Mellon University is looking for a postdoctoral researcher to join our team. By 2050, older adults will comprise 22% of the global population, placing greater demand on traditional healthcare systems. Meeting these challenges demand technical innovation at the interface of hardware, software, and intelligence. Our mission is to create scalable mobile systems for physiological intelligence using wireless sensing, signal processing, and AI. We invent bio- and physics-inspired hardware systems to decode hidden signals from the body and environment, and enable new sensory capabilities for millions of humans and machines.
Our innovations include using radar to contactlessly detect muscle fatigue and measure blood pressure, repurposing cheap earphone speakers to listen to heart valve mechanics, smartglasses that sense eye muscle signals to enable auto-focusing lenses for age-related vision loss, a smartphone attachment that isolates a speaker's voice in a noisy restaurant as assisitive listening aid, and transforming a standard tablet touchscreen into a sensor that can detect microliter-scale DNA samples.
Our work has been published in venues like SenSys, MobiSys, CHI, UIST, IROS, and Nature-family journals (Communications, Biomedical Engineering, Digital Medicine).
Pittsburgh is a great city, CMU is an amazing place to do research, and the lab has a collaborative, supportive culture. If this sounds like a fit, or if you know someone it might be a fit for, I'd love to hear from you. Feel free to DM me or email me at justinchan@cmu.edu. I will be at CHI 2026 and SenSys 2026 this year where our lab will be presenting full-length papers, feel free to come find me for a chat if you're interested.
