Crystal Qian is a senior research scientist and software engineer with 11 years of experience building scalable ML and data infrastructure at Google, DeepMind, and Google AI. She bridges research and production, contributing to core workflow tooling like Apache Airflow (improving GCP Dataproc integrations) and interactive ML interpretability front-ends such as the LIT embeddings projector. Her background spans backend systems, data pipelines, and UI polish—evidenced by contributions to ASP.NET tooling and GCP training DAGs—so she comfortably navigates both low-level code generation and cloud-native pipelines. Based in New York with degrees from Princeton and MIT, she combines rigorous CS foundations with economics-and-policy insight, enabling technical work that considers broader product and societal context.
