Summary
👤
Senior🎓
Top SchoolHao He is a data scientist with 10 years of experience specializing in social media, trust and safety, and computational linguistics, currently working on R&D in AdTech at Zefr. He blends academic rigor from an MS in Data Science (Computational Linguistics) at UBC with hands-on industry work including a recent contract at Meta and research roles across Canadian institutions. Hao has applied machine learning to real-world problems from satellite analytics at Environment and Climate Change Canada to healthcare systems at McGill, and completed an ML capstone that informed production-ready solutions. He contributes backend code to community projects like the WeBWorK open problem library, showing a practical interest in algorithmic problem design and iterative content tooling. Comfortable across infrastructure, middleware, and NLP pipelines, he brings a cross-domain perspective that connects statistical foundations to product-facing safety systems. Based in Canada, Hao pairs curious, research-driven thinking with pragmatic engineering to improve how social platforms detect and manage harm.
