Current focus

Current work includes medical-data and patient-safety research with Ajou University Hospital and the manuscript From Fault Tolerance to Modular Authority. Other work keeps its own period and status.

Separate records

• Ajou University Hospital medical data / patient safety — nursing informatics, patient-safety data workflows, actigraphy-informed shift-work sleep modeling, and clinical knowledge representation.
• Personal research — the current ACM Computing Surveys manuscript on consensus genealogy and authority, plus completed consensus, PoW, DeFi, and assessment work.
• Patents — registered intellectual property remains a separate category instead of being folded into personal research.
• Infrastructure & systems — FarmBit is the long-horizon compute-and-energy direction; AROL compounds memory, evidence, and execution toward AGI.
• Venture — Project Alchemist records a bounded period where product, technology, and decisions met in one accountable role.
• Research projects, teaching, and career history — defense authentication, DID, railway interoperability, C-ITS, DeFi metrics, digital-twin resilience, startup CTO/PM work, app release, KT Aivle tutoring, KRAFTON Jungle assistant instruction, Kyonggi University SW mentoring, and CITI research-readiness training.

Evolving system

AROL turns source review, persistent memory, evidence, verification, and execution into one compounding loop. Its direction is AGI: progress through verified cycles, not a claim that the destination is already reached.

Operating rule

Verified publications link to public DOI, patent, publisher, Scholar, or project sources. A relationship is shown only when the source record directly supports it; shared authorship or timing is not treated as one umbrella story.
