Postdoc @Emory University

Ph.D. @University of Tennessee, Knoxville

I will be joining University of Oklahoma as an Assistant Professor (Tenure-Track) in January 2025. I am actively recruiting Ph.D. students starting Fall 2025. If you're interested in Mobile Sensing, Cybersecurity, Human-computer Interaction, and Smart Health, please feel free to contact me.

Greetings! Welcome to my homepage. I am a Postdoctoral Researcher in the Center of Data Science at Emory University, working with Dr. Xiao Hu. I completed my Ph.D. at Min H. Kao Department of Electrical Engineering and Computer Science at University of Tennessee, Knoxville, under supervison of Dr. Jian Liu. My research interests encompass the areas of mobile sensing & computing, human-computer interaction, and cybersecurity & privacy. Particularly, I utilize machine learning and signal processing techniques to create next-generation applications for human-computer interaction, smart health monitoring, and identifying potential security/privacy issues on IoT devices.

Misc.

I enjoy watching movies & reading detective fictions in my leisure time. "The Pursuit of Happyness", "Batman: The Dark Knight" and "Tokyo Godfathers" are my favourites.
I also enjoy swimming & watching NBA games.
