About Me

I am a Ph.D student in the Computer Science Department at UC Davis. My advisor is Prof. John Owens. My research interests span across general-purpose computing on graphics processing units (GPGPU,also known as GPU computing), computer graphics, parallel algorithms programming and data compression. Recently, I've been particularly interested in implementing classic algorithms on GPU and large-scale GPU computing.

Before coming to Davis, I received a B.S.E.E. degree in Information Science and Electronic Engineering from Zhejiang University and a CKC Honors Certificate from Chu Kochen Honors College, Zhejiang Univeristy. My research advisor was Prof. Erping Li. In 2012, I was exchanged to National Chiao Tung University for a semester in the Department of Electronics Engineering, during the same time, I worked with Prof. Tzonglin Wu in his EMC research group in National Tainwan University.

Projects

CUDPP

CUDPP -- CUDA Data Parallel Primitives Library

CUDPP 2.2 release czar and developer. The library is on github.

SA

Fast Parallel Suffix Array on the GPU: Implemented a linear time suffix array construction algorithm, skew, on the GPU making algorithmic improvements to the previous state-of-the-art work with a speedup of 35%. It has been added as a new primitive in CUDPP 2.2 and has been used in the BWT-based lossless data compression tool.

YELP

Communities for A Better Yelp: A project from Yelp Data Challenge where we implement a new method for calculating business ratings that is based on community detection. The project is on github
