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