Welcome to Yafeng Yin's Homepage

Short Biography

I am an assistant researcher of Department of Computer Science and Technology at Nanjing University. I received my Ph.D. degree from Nanjing University in 2017 under the supervision of Prof. Sanglu Lu and Prof. Lei Xie, and received my BE degree from Nanjing University of Science and Technology in 2011. From Sep. 2014 to Sep. 2015, I was a visiting research scholar in Department of Computer Science at the College of William and Mary, supervised by Prof. Qun Li and sponsored in part by China Scholarship Council (CSC).


Research Interest

My research interests focus on human activity recognition, wearable computing, augmented reality, etc., including algorithm design and system implementation.

I am recruiting motivated Ph.D. or master students who would like to work on the above-mentioned areas. Undergraduate students who are interested in the related topics are also encouraged to contact me.
