My current research area is security and privacy in mobile and IoT devices. I created a system called ReCon, which exploits machine learning to detect personally identifiable information(PII) leaks in network traffic. Thus far, ReCon has received great public attention and attracted thousands of users. The project is currently funded by a Data Transparency Lab grant. Given the success of ReCon, we extend it to IoT devices and receive a new grant from DHS working on privacy in IoT.
The goal of my work is to enable any network user to understand and control the personal information exposed by mobile and IoT devices over the Internet. I believe that my work opens a new avenue for research on online privacy, and provide opportunities to improve privacy for average users.
Before I joined the networking research community, I did research in Human Computer Interaction for over two years, and also spent one year working on machine learning problems. I have extensive experience in writing software systems, including various engineering and research areas such as network trace analysis, human computer interaction, health informatics, behavior change theory and machine learning.
