Physician · Researcher · Building & evaluating AI

Physician by training,
builder by instinct —
figuring out where AI
and medicine go next.

I'm a doctor who got pulled into AI. Right now I build and evaluate AI agents inside a real company; what I'm really after is bringing that discipline back to my roots — medicine. I'm in San Francisco for a few months to meet people and find out where it goes next.

If something here resonates, that's reason enough to talk.

Where I'm coming from

A physician and
researcher, first.

I trained and practised as a physician, then spent years in research. My doctoral work at RWTH Aachen — graded summa cum laude (the highest distinction) — developed a method around antipsychotic-induced weight gain, and is published in the peer-reviewed literature.

I defended that thesis with an AI research system I built myself — a second brain that turned analyses that used to take me weeks into minutes. That experience was the eye-opener: I shouldn't be the only physician with access to that kind of leverage.

This is the lens I see everything through. Medicine taught me to care about evidence, edge cases, and the gap between what looks promising and what actually helps a real person. That instinct is exactly what I bring to AI.

What I'm doing now

Building with AI,
inside real companies.

Right now I help companies put AI to work in ways that actually pay off — finding the high-leverage automations, then building them. With Bobshop, a European retailer, that has meant turning everyday AI tools into real operating leverage rather than novelty.

Lately the work has converged on one discipline: evaluation. Most AI agent projects die in production — not because the model is weak, but because nobody can prove the system works. At Bobshop I built that proof: an eval pipeline that graded 248 production outputs against a six-dimension rubric, LLM-as-judge, traced in Arize Phoenix — failure modes named, traced, and fixed.

I think of this as honing the craft. Every company I help is a step closer to the thing I really want to build: AI that meets people where medicine and health actually live. The practical work and the bigger goal aren't separate — one funds and sharpens the other.

There's a focused engagement for exactly that — a short, practical audit-to-build that turns AI into real operating leverage.

The idea I keep circling

In regulated medicine, the bottleneck isn't building the agent — it's proving it's safe enough to deploy.

That proof takes clinical judgment, and that's the part engineers can't do alone. I'm one of the few physicians who can build the system and grade it — and I think that's exactly the evaluation layer medicine is missing.

The shape I keep coming back to: AI-native healthcare services that own the outcome instead of selling software — with a continuous evaluation layer of golden cases, failure modes, and grading rubrics that compounds into something defensible. If you're thinking about the same problem, I want to talk to you.

What I'm open to

Curious about a lot.
Open to more.

I weigh things carefully before I commit — and what draws me in is people and problems that are genuinely interesting and push something forward. If one of these sounds like you, that's reason enough to talk.

Building in AI × health

The north star. Where I ultimately want to build or join — AI that genuinely helps people stay well, proven with the eval discipline medicine demands.

Joining or talking to startups

Not just selling to companies — I'd genuinely like to meet teams I could join, help, or simply learn from.

Helping a company, or a friend's

If someone you know is trying to use AI well and not sure where to start, send them my way.

Co-founding or advising

The right idea, the right people. Especially if you've shipped in healthcare-grade environments or built eval harnesses — I'm open to going deep as a founder or advisor.

AI broadly, not only medicine

Medicine is the direction, not a fence. Interesting AI problems in any domain get my attention.

Just comparing notes

Some of the best conversations start from pure curiosity. If you're building something interesting, I'd love to hear about it.

Get in touch

If any of this resonates,
I'd love to hear from you.

Whether you want to work together, compare notes, or simply say hello while I'm in town — reach out. I read every message.
