Developer of Gunrock, a high-performance CUDA library for graph-processing designed specifically for GPUs. It uses a high-level, bulk-synchronous, data-centric abstraction focused on operations on a vertex or edge frontier. Currently focus on Performance Modeling/Characterizing and improving the framework to better support mutable and more advanced graph primitives.

Collaborated with Yangzihao Wang, together we implemented a novel scene classification method which combines Convolutional Neural Network (CNN) and Spatial Pyramid Pooling to generate high-level context-aware features. We achieved better recognition rate than the state-of-the-art method on the challenging MIT Indoor-67 dataset using only the deep features trained from ImageNet.
Implemented parallel Boruvka's minimum spanning tree (MST) algorithm using Gunrock's data-centric programming model. Achieved up to 120X speedup against the serial CPU Boost graph library (BGL) implementation for real-world road networks, open street maps (OSMs), Delaunay graphs, and many long-diameter fully-connected synthetic datasets.

Designed and implemented mobile IPv6 protocol using filtering technology. Upgraded a NDIS filter driver to filter bypassing data packets to extend roaming capabilities and merged into standard IPv6 protocol.
