This writeup was developed with the assistance of Claude (Anthropic) as an AI research and writing collaborator. The author arrived with substantial work already completed: a fully executed Jupyter notebook with Kyte-Doolittle analysis and ESMFold structure predictions across four protein variants; multiple ESMFold PDB structure files; a Twist Bioscience codon-optimized FASTA sequence; a Benchling construct with annotated restriction sites; a pre-written abstract and motivation grounded in Sutherland’s Ultimate Display; three fully articulated project aims; and prior presentation materials from the HTGAA course. The workflow was conversational and iterative: Claude reviewed all of these materials, then prompted the author with targeted questions section by section. The author provided conceptual framing, corrections, and key ideas — including the primitives model for Aim 2, the personal biofabrication ethics framing, the jitter algorithm as the central synthesis challenge, hygroscopic actuation terminology, and the baseline casein bioplastic as the experimental starting point — while Claude structured and articulated those ideas into prose, scaffolded missing sections, and flagged inconsistencies for review. All scientific ideas, experimental results, design decisions, and framing are the author’s own.
