I am a Postdoctoral Fellow at Sensorweb Lab, School of Electrical and Computer Engineering (ECE), College of Engineering, UGA. I have a PhD in Computational Geophysics from School of Geosciences, the University of Oklahoma, a M.Eng. degree from Department of Automation, Tsinghua University and a B.Eng. degree from School of Automation Science and Electrical Engineering, Beihang University.
My research focuses on developing methodologies for high dimensional, streaming, non-stationary, complex data analytics, and applying these methods within an algorithmic workflow to solve real-world problems. My broad research interests are in dynamic signal analysis, IoT & CPS security, machine learning and engineering geophysics, with applications to distributed sensor networks, smart healthcare, power grid, power electronics, and infrastructure security.
The curiosity of various signal properties drives my research. I have conducted researches in the broad area of streaming dynamic signal analysis and data science. My recent research activities involve online, real-time, high dimensional, non-stationary, non-linear signal analysis; machine learning and deep learning; modeling and mining of large scale networked data; incentive mechanisms for cyber-physical security; biomedical signal characterization; connected smart technologies, smart healthcare, etc. In summary, my work focuses on:
- Non-stationary dynamic signal analysis, including seismic signal, power electronics signal, etc.
- Engineering-driven data analytics for real-time "big data" generated from complex systems;
- Physics based data-driven models to effectively analyze high-dimensional data structure;
Having the joint background of electrical engineering and computational geophysics, I have taken part in diverse projects, for example, Internet of Things (IoT) security, Cyber Physical Systems (CPS) security, advanced signal processing, subsurface imaging, infrastructure security, power systems attack diagnosis, smart healthcare and so on. I have collaborated across different disciplines, and my broad research interests include:
