Dartmouth College provost Santiago Schnell resigned on October 30, 2026, after an advisory committee concluded he failed to disclose significant AI use in an academic paper submitted to ChemSystemsChem and a Washington Post op-ed published August 9, 2026, despite publisher disclosure requirements. The committee cited "insufficient cooperation," noting Schnell provided his Dartmouth laptop but withheld logs from personal LLM accounts and declined to meet with investigators. However, the committee accessed his Dartmouth-linked Claude enterprise account, revealing he used the LLM for revising papers, debugging code, and generating or editing figures. Specific prompts included asking Claude to simulate a peer reviewer with expertise in nonlinear chemical dynamics and mathematical chemical kinetics to critique a manuscript prior to submission. Schnell maintained he used AI as an editorial aid and discussion partner, telling Semafor he employed chatbots to "refine a few arguments" and "check for grammatical errors," and informing a journal editor he used AI as an "editorial tool" to "help refine sentences, improve clarity, and the expression of arguments." He claimed he did not disclose this usage because he "did not understand that this type of AI-assisted editing required disclosure." The case highlights ambiguity in institutional and publisher policies regarding disclosure thresholds for AI-assisted editorial workflows versus generative authorship.
