Summary
🤩
Rockstar🎓
Top SchoolSitong An is an algorithm developer and machine learning researcher who bridges cutting-edge ML with experimental high-energy physics, currently interning at Hudson River Trading and completing a PhD at Carnegie Mellon. With eight years of experience across CERN, DESY, Fermilab and industry internships, Sitong has applied graph neural networks, pruning/quantization workflows, and novel boosting techniques to real-world physics and genomics problems. A Marie Skłodowska-Curie fellow and INSIGHTS ITN alumnus, they have translated academic ML advances into production-oriented benchmarks and client-facing computer vision adaptations at KPMG Netherlands. Comfortable in Python, C++, ROOT and parallel computing, Sitong combines deep domain expertise in particle physics with practical algorithm engineering for low-latency, high-throughput environments. Notably, they’ve automated hyperparameter and working-point optimization pipelines and adapted state-of-the-art research into deployable solutions beyond academia.
