AI × Epidemiology

Health data into decisions.

I am a PhD epidemiologist who writes the software — so I can build the system, and tell you whether its answer is actually right.

BACKDOOR BACKDOOR DIRECT EFFECT CONFOUNDER Age · SES EXPOSURE Phys. activity MEDIATOR BMI OUTCOME CVD risk
BMI is a mediator, not a confounder. Adjust for it and you erase the effect you came to measure. Correct set: {Age, SES}.

I judge the output

Not whether it sounds right — whether it is epidemiologically, clinically and methodologically correct.

I build the system

Nothing that decides a number lives in a UI component, and the tests run inside the build.

I run a health institution

By day. Which is why the tools assume messy data, thin staffing and a decision due this week.

In production

Running right now.

Every link opens something live, or source you can read.

Draw the DAG, get a formally verified adjustment set and the R/Python code.

Three ways to bring me in.

AI strategy for health

  • Data and readiness assessment
  • Use-case prioritization
  • Build-vs-buy, cost per inference
  • Governance and PHI handling

Epidemiological method

  • Study design and causal identification
  • DAGs and adjustment sets
  • Systematic review and meta-analysis
  • Surveillance design and evaluation

Custom AI development

  • Clinical decision support
  • Scientific RAG over your corpus
  • Agentic workflows and automation
  • FHIR integration, PHI-safe architecture

Discovery call, free

Thirty minutes. If AI is the wrong instrument, I say so.

02

Scoped proposal

Deliverables, timeline, fixed price, stated assumptions.

03

Delivery you can audit

Code, tests and rationale — so your team maintains it without me.

Insights

Methods, models, and what survives a clinic.

Cuando ajustar inventa una asociación: el colisionador

Hay un error de ajuste peor que bloquear un efecto: crear uno que no existía. Y los datos no te van a avisar.

What a health ministry actually needs from an AI vendor

Four things that decide the deal, none of which are the model — written from the side of the table that has to sign and answer for it.

The measles pathway had to work without signal

The connection drops. The patient is still in front of you. That sentence was the whole specification.

About

Vicente Ernesto González-Aramayo, PhD

For a decade I did the serious version of this work: a PhD in epidemiology, National Director of Epidemiology for a ministry of health, project coordinator with PAHO/WHO, graduate faculty in research methodology.

And I kept hitting the same wall: the methods exist, the papers exist — what doesn’t exist is someone who turns rigorous science into working software. So I founded IAM-Studio, an AI studio born inside public health rather than imported from tech. What we don’t build is a generic chatbot with a health sticker on it.
