01 / SELECTED WORK

Complex challenges.
Practical applications.

From anticipating patient risk to making sense of clinical records. A selection of my work in healthcare AI.

RECENT WORK / 2025

The Evolve
Collaborative.

AI-powered analytics for better hospital performance. A collaboration between Beamtree and the NHS Confederation, bringing benchmarking and predictive forecasting to NHS trusts.

02 / CLINICAL NOTES ANALYSIS

From clinical text
to clearer insight.

Extracting medical information from unstructured notes to support clinical review and better connected patient data.

  • Natural language processing
  • Information extraction
Inside the project

The challenge

Important patient information lives in free-text notes that are difficult to analyse consistently at scale.

The work

Clinical NLP to convert unstructured text into structured information and surface potential medication interactions and adverse events for review.

03 / PATIENT DETERIORATION

Earlier signals.
More time to act.

Analysing vital signs and laboratory results to identify deterioration risk and support timely clinical intervention.

  • Predictive modelling
  • Clinical decision support
Inside the project

The challenge

Give clinical teams an earlier, actionable view of patient risk across a ward or hospital.

The application

Real-time patient monitoring that brings vital signs and laboratory results together to support risk assessment.

Product evidence: Beamtree reports a 5% reduction in length of stay in a published ADI implementation study. This is a product-level result, not an individual performance claim.

04 / AUTO CLINICAL CODING

Less manual coding.
More useful information.

Combining LLM agents with retrieval-augmented generation to turn clinical records into ICD and procedure codes.

  • LLM agents
  • RAG
  • Clinical coding
Inside the project

The challenge

Clinical coding is a detail-intensive process that depends on understanding both the record and the relevant coding guidance.

The work

Applying language models and retrieval to support code generation, reduce repetitive coding work, and keep relevant clinical context close to the task.

03 / A LITTLE ABOUT ME

Luke Cao.

Guanhua Cao / Sydney

Technical curiosity.
A human purpose.

I’m a senior machine learning engineer at Beamtree in Sydney, focused on a question that keeps my work grounded: how can this help the people delivering care?

My experience spans hospital forecasting, clinical text analysis, predictive monitoring, and automated clinical coding. Across these areas, I focus on accurate, interpretable models and applications that fit the healthcare decisions they support.

I enjoy working at the meeting point of complex data and practical problems—turning the former into something people can actually use.

EXPERIENCE / BEAMTREE

Healthcare AI.
Built at Beamtree.

My current work centres on production machine learning and the healthcare applications it supports—from hospital forecasting to clinical coding.
