Short Biography

Jianqiu Xu got his bachelor and master degrees from Nanjing University of Aeronautics and Astronautics in 2005 and 2008, respectively. From 2008.9 to 2012.9, he was a Ph.D student supervised by Prof. Dr. Ralf Hartmut G¨¹ting (retired in February, 2021) from FernUniversität in Hagen, Germany. He mainly focused on moving objects with multiple transportation modes and got his Ph.D in July 2012, with the score "magna cum laude" (from Latin, meaning with great honor). He is a member of ACM SIGSPATIAL (since 2014), ACM (since 2019) and IEEE (since 2019).

Ph.d Thesis, Moving Objects with Multiple Transportation Modes, July, 2012, with the score "magna cum laude" (from Latin, meaning with great honor).
