Suraj Ranganath
Hello 👋
I like doing research and I like to build. My work moves across AI agents, graph machine learning, safety evals, world models, identity security, EEG tooling, and learning analytics.
Previously, I helped build BalkanID Copilot, an agentic identity-security product used by enterprise customers. This summer I am building at C1.
