Worth keeping because he is one of the original RWKV coauthors who clearly did not stop there: his public work moves into production AI for crisis intelligence, security-aware infrastructure tooling, and later open-LLM experimentation.
Worth keeping because it connects an early RWKV byline to a much more visible later research program in agentic AI, biomedical discovery, and code-focused evaluation, which makes the page far more useful than a one-paper ghost profile.
