Brian K. Fung

• Led cross-hospital medication workflow and security initiatives across seven hospitals, including an enterprise authentication transition affecting 3,500+ nurses.

• Led EHR training for a 40+ FTE pharmacy department during conversion from McKesson Horizon Meds Manager to Allscripts while maintaining clinical pharmacist responsibilities.

Independent product work, started during a period of full-time family caregiving, which is where haau3 originated.

• Conceived and built haau3, a consumer caregiving platform that unifies longitudinal health records and helps patients and caregivers securely access, understand, and share health information; sole builder from concept through general availability, setting the roadmap across identity, interoperability, conversational AI, and caregiver workflows.
• Took haau3 to general availability in the CMS Health Tech Ecosystem for both the Conversational AI and Kill the Clipboard use cases, recognized by CMS at the program's first-anniversary event in July 2026; among the first seven apps listed in the CMS Medicare App Library, sourcing records through a TEFCA QHIN and CMS Aligned Network.
• Built and iterated Cora, a multilingual text- and voice-based conversational AI assistant grounded in patient-authorized records; combined Gemini Live, RAG, deterministic knowledge retrieval, and source-linked explanations, evolving the UX from text to speech-to-text to speech-to-speech based on caregiver feedback.
• Launched Unscripted Rx from 0-to-1 as a pharmacy workforce and recruiting discovery product with 30,000+ connected entities; grew it organically to 10,000+ monthly views with top-10 Google search visibility and built AI-assisted job-posting ingestion and content normalization to reduce manual population and improve coverage.
• Built medlistIQ, an auditable medication-reconciliation API that normalizes and deduplicates fragmented medication data; owned product concept, UX, data model, architecture, and implementation end to end.
• Advise CEOs, CTOs, CPOs, and product and engineering leaders on AI-enabled product strategy, platform architecture, and EHR-integrated workflows.

• Partnered across Product, Engineering, UX, Research, Clinical, Legal, and Privacy to translate ambiguous user and clinical needs into product requirements and implementation-ready architecture for Verily Me and Lightpath, supporting multiple patient-facing digital health launches.
• Led semantic and workflow architecture using BPM+ and FHIR, producing 100+ CMMN, BPMN, DMN, and data artifacts that connected user journeys and clinical logic to APIs, decisions, and data contracts.
• Directed enterprise FHIR governance across product, engineering, and informatics teams, defining 200+ implementation guidance artifacts, semantic models, review patterns, and developer tooling.
• Designed evaluation frameworks comparing deterministic clinical reasoning with frontier LLM approaches for AI-assisted type 2 diabetes decision support, clarifying accuracy, explainability, safety, and implementation tradeoffs.

• Led end-to-end product and workflow transformation across four Epic module implementations, covering antimicrobial stewardship, infection control, clinical decision support, and Willow pharmacy, spanning 80 hospitals and clinics within a $1.5B enterprise program, from discovery and requirements through validation, training, rollout, and iteration.
• Modernized a 25+ year rules-based antimicrobial monitoring platform, converting 75+ custom legacy rules from CBAM and TheraDoc into Epic through 2.5 years of system discovery, workflow redesign, decision-support configuration, testing, and production deployment.
• Built NHSN regulatory reporting for CAUTI, CLABSI, SSI, VAE, and LabID events, plus internal surveillance reporting for bloodstream infections, carbapenem-resistant organisms, and multidrug-resistant organisms, with a distribution strategy designed for low ongoing maintenance.
• Designed physician-facing reminder alerts for catheter-associated urinary tract infection, central line-associated bloodstream infection, and umbilical catheters, and coordinated the enterprise prevention workflows behind them.
• Enabled bidirectional laboratory interoperability between Mayo's SOFT laboratory system and two of the largest external reference labs, Quest Diagnostics and Labcorp, integrating 10,000+ external microbiology records by mapping laboratory tests, organisms, and susceptibilities with LOINC and SNOMED CT.
• Converged an enterprise list of indications for all systemic antimicrobials and built them into Epic, alongside restricted medication workflows using alternatives, order questions, best practice advisories, and scoring.

MPH practicum and capstone placement, concurrent with Mayo Clinic. Practicum supervisor: Debbie Bucci. Capstone advisor: Thomas Mason, MD.

• Assisted in drafting the electronic prescribing sections for the ONC's Cures Act Final Rule, fulfilling provisions of the 21st Century Cures Act.
• Assisted in summarizing public comments on the ONC's Cures Act proposed rule during the notice of proposed rulemaking for electronic prescribing.
• Analyzed the implications of the 21st Century Cures Act on clinician burden attributable to health information technology and electronic health records, work that became the MPH capstone.
• Coordinated a one-day national stakeholder symposium on patient matching for prescription drug monitoring programs.

Independent research; open evaluation harness released publicly, with retrieval, classification, and string-matching baselines.

Nine self-paced courses and 137 lessons on AI, APIs, interoperability, and software development for clinicians entering engineering, now extended with live cohort instruction.

Pledged the Kill the Clipboard and Conversational AI use cases, both of which reached general availability, and the Year 2 advanced scheduling and consumer real-time benefits categories.

Workgroup contributor. Translated multi-organization scheduling workflows into a balloted FHIR implementation guide with examples and developer-facing artifacts.

Awarded to haau3 for reaching general availability as a patient-facing app in the Conversational AI and Kill the Clipboard categories.
