Building Secure & Private Cyber-Physical Systems

The Cyber-Physical Systems Laboratory (CPSLab) at Marquette University is directed by Dr. Keyang Yu. Our mission is to advance the design of data-driven computer systems with an emphasis on improving cybersecurity and user privacy across Cyber-Physical Systems (CPS) and the Internet of Things (IoT).

Our work spans multiple technical fields including Embedded Systems, Computer Networks, AI@Edge, Tiny Machine Learning, and Distributed Computing. We tackle real-world privacy and security challenges in smart homes, smart buildings, and renewable energy systems.
