I am a PhD student at CVLAB, EPFL, under the supervision of Prof. Pascal Fua and works closely with Dr. Mathieu Salzmann. Prior to that, I graduated from Communicate Systems, EPFL, in April 2017. I received the Bachelor of Engineering degree from the School of Electronic Engineering in University of Electronic Science and Technology of China (UESTC) in 2014.
My research interests lie in the field of Computer Vision, Machine Learning and Robotics. Currently, I am focusing on crowd counting with applications in drones.
