Welcome to Ziqiang Shi(石自强)’s homepage.

About

I am a Senior Research Scientist and Senior Research Manager at the Fujitsu R & D Center in Beijing. My current research interests include music, audio, speech, and image signal processing. I obtained my PhD degree in the spring of 2013 from the Harbin Institute of Technology in computer science under the supervision of Prof. Jiqing Han. Additionally, I obtained a Master of Science in the summer of 2008 in computer science from the same institute learned from Prof. Haifeng Li. I earned a bachelor’s degree in computer science from Northeastern University in Shenyang, where I was admitted without Chinese GAOKAO. Last, but certainly not least, I got married to my wonderful wife Lei Shi in the summer of 2012. (By the way, I am originally from the suburbs of Yangzhou City, Jiangsu province)
