Summary
🤩
Rockstar🎓
Top SchoolTingwu Wang is a Staff Research Scientist at NVIDIA with 11 years of experience bridging machine learning research and real-world systems for games and robotics. He earned a PhD in machine learning from the University of Toronto with ties to Vector Institute and NVIDIA, and was advised by Sanja Fidler and Jimmy Ba. At NVIDIA he’s progressed from research intern to staff scientist working on generalist embodied agents and physics-based character animation using reinforcement learning. He’s an active open-source contributor in graph ML, integrating GPU-accelerated cugraph-ops into major libraries like PyTorch Geometric and DGL to speed up GNN layers such as SAGEConv, GATConv and RGCNConv. Based in California, he combines deep academic rigor with hands-on engineering to push scalable, GPU-first solutions for embodied AI. An under-the-radar strength is his practical ability to port research models into production-grade, high-performance code paths.

Graph Neural Network Library for PyTorch
Role in this project:ML Engineer
ML EngineerContributions:1 review, 4 PRs, 10 comments in 7 months
Contributions summary:Tingwu contributed to the `pytorch_geometric` library by implementing and integrating optimized graph neural network models using the `cugraph-ops` package. Their primary focus was on creating GPU-accelerated versions of existing GNN layers, specifically `SAGEConv` and `GATConv`, leveraging the performance benefits of `cugraph-ops` for faster execution. They also worked on integrating RGCNConv model using cugraph-ops, which involved adapting the codebase to support the new functionalities.
