The DAISY Lab is led by Prof. Yingying (Jennifer) Chen. You can always stop by her office at Burchard Building 210 to have an inspired research discussion!


As wireless and sensor networks continue to have an important impact on our life and eventually become a part of our social fabric, the network infrastructure will increasingly become the tempting targets for malicious attacks. Further, with the huge amount of information transmitted over the networks and eventually displayed in the Internet, the main question that people asked about is what should constitute “fair use” of the information. The Data Analysis and Information SecuritY (DAISY) Laboratory focuses on both addressing the problems in information security, system privacy, and data integrity using statistical approaches and machine learning techniques, as well as building test beds to facilitate research in these areas.

Current Research Areas

  • Cyber Security and Privacy
  • Mobile Healthcare and its Security Issues
  • Mobile Computing
  • Pervasive Computing
  • Wireless Networks and Sensor Networks

 Project Demonstration

1. Fine-grained Sleep Monitoring Leveraging Home Wi-Fi Networks

2. Sensing Driver Phone Use to Reduce Driver Distraction Caused by Cell Phone Usage

3. Look Up: Enabling Pedestrian Safety Services via Shoe Sensing

The project has received the Award of Solutions for Pedestrians & Cyclists – Large Organization Recognition in the Connected Intersections competition sponsored by AT&T.

4. BigRoad: Scaling Road Data Acquisition for Dependable Self-Driving
