Biography

I have completed PhD in Computer Science at Graduate Center, City University of New York. My advisor is Prof. Jianting Zhang. Prior to CUNY, I received my Bachelor's degree in Computer Science from University of Science and Technology of China, Hefei, China, in 2009. My current research interests include High Performance Geospatial Computing using GPGPUs, Big Spatial Data Processing, Spatial Databases, and GIS applications.

Project

Spatial Data Processing on GPGPUs

coming soon

ISP: Spatial Data Processing on Impala

ISP is a system based on Cloudera Impala, which includes a set of spatial operations and an efficient spatial join module accelerated by not only multicore CPU but also GPUs.
