Yiqun Liu studied Communication Engineering at Fudan University from 2003 and received Bachlor of Engineering (BoE) in Jul. 2007.

From 2007 to 2012, he furthered his study at Universität Stuttgart and concentrated on Signal processing. He received Dipl.-Ing in March 2012 and is currently working at the Institut for Informationsverarbeitung (TNT) of Leibniz Universität Hannover since December 2012.

His research interest is in the field of video coding. From December 2012 to August 2013, he was concentrating on the scalable extension of HEVC (High Efficiency Video Coding). Since Sep. 2013 he has been working on the topic "Motion Blur Compensation", which is an extension to the inter-frame prediction in the current standard. Another research topic of his is the quantization method in HEVC, where he tries to apply "Vector quantizer" instead of the conventional way combined of transform and scalar quantization.
