Snowball Lab is part of the Department of Computer Science at Purdue University. We create novel sensing technologies, signal processing and machine learning methods, low-power systems, and embedded intelligence to address important real-world problems. Our work spans applications in wearable computing, health, and human-computer interaction. We are particularly interested in building systems that are practical for everyday life, scalable beyond research prototypes, and robust for long-term deployment in real-world settings.
