I am a 5th-year PhD candidate at UC Davis being jointly advised by Prof. John Owens and Prof. Aydin Buluc (UC Berkeley, LBL). Part of my work is funded as a GSRA at LBL. I received a BASc in Electrical Engineering from University of British Columbia. My research interests include graphic processing unit (GPU) computing, parallel computing and graph processing.


High-performance implementation of GraphBLAS on GPU using optimizations from Gunrock and automatic direction-optimization from Ligra. C++/CUDA header-only library.

High-performance graph primitives on GPU. C++/CUDA shared object library.


Reviewer for the following conferences and journals:

  • ACM Transactions on Parallel Computing (TOPC)

  • ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games (I3D)

  • IEEE International Parallel & Distributed Processing Symposium (IPDPS)
