Human-Centred AI · Health Systems · Data Governance

Sajjad Karimian

I study why AI systems fail the people who depend on them — and how to design them so they don't.

With a background spanning hospital IT, clinical data analysis, and academic research, I work at the intersection of healthcare informatics, human factors, and responsible AI. My focus is on the gap between how AI is built and how it is actually used — in clinical workflows, organisational processes, and real-world deployments.

My Path

From Server Rooms to Clinical Systems

01

Where it started — Hospital IT

I spent over seven years managing servers, web infrastructure, and IT systems, including inside a clinical environment at Mashhad University of Medical Sciences. I was close enough to healthcare to see how data moved — or failed to. Systems were designed without asking the people who used them. Workarounds were everywhere. Data sat in silos. Reports reflected what was easy to record, not what was clinically meaningful.

02

The question that changed direction

Why do technically sound systems get abandoned, gamed, or ignored in healthcare? I moved into Medical Informatics and then Computer Science research to find a structured answer. At UCD, working on ontology engineering, socio-technical systems analysis, and human factors, I found that the failure point is almost always the same: the system was designed around data flows, not around people and their context.

03

Bringing it into practice — St. James's Hospital

During my placement at St. James's Hospital Dublin, I analysed data collection, quality management, and reporting practices across a major acute hospital. I documented data quality gaps, mapped fragmented workflows, and produced structured outputs for clinical and senior operational stakeholders. The problem wasn't the data — it was the mismatch between how the system was designed and how clinical work actually happens.

Where I work now — Human-Centred AI

Across the VICTORY and ID4AI projects at UCD, I contribute to healthcare AI innovation, inclusive design research, and AI governance. My work sits at the intersection of three things: understanding how AI systems interact with real clinical workflows, ensuring data is transparent and trustworthy, and helping organisations think through what responsible AI deployment actually requires — not just technically, but organisationally and humanly.

What I Actually Do

Not an AI developer. Not a pure data scientist. Something more specific.

Systems Analysis

Understanding how data and decisions actually flow

I map clinical and organisational systems to identify where data quality breaks down, where accountability is unclear, and where AI interventions will create friction rather than value.

AI Governance & Trust

Making AI deployable — not just buildable

Using socio-technical systems analysis and human factors methods, I assess how AI systems build or erode trust inside organisations, and what governance structures support responsible adoption.

Human-Centred Design

Bridging clinical need and technical capability

I work across multidisciplinary teams — healthcare, research, and technology — translating between what clinicians and users need and what systems can realistically deliver.
