Portrait of Carl Luis Pöhl

Carl Luis Pöhl

I build and evaluate AI for medical decisions.

Munich · open to relocation

I'm a computer-science graduate and a final-year medical student pursuing two doctorates, one on AI for cancer treatment and one on machine learning for Parkinson's progression. My work spans AI that helps doctors choose treatments, testing whether medical AI can be trusted, and AI products for paying clients. I've also co-founded three ventures, and ConcordAInce, built on my PhD, got a Y Combinator interview.

I grew up between Mexico, Spain, Germany, Japan and Norway, finished school in Tokyo at 16, and studied in Hong Kong (HKUST), Lausanne (EPFL), Budapest (Semmelweis), Aachen (RWTH) and Dresden (TU Dresden).

Research

PhD Candidate (Dr. rer. medic.)

Jan 2025 – present

Dept. of Urology, University Hospital Dresden

Collaborators: Jakob Kather (Kather Lab), Lars Hilgers. Supervisors: Sherif Mehralivand, Marcus Sondermann.

  • –Secured four university hospitals to test the system. Wrote all ethics submissions through approval. Testing on new patients is planned from Q4 2026.
  • –Benchmark. Compared 44 setups across six AI designs on 500 real patient cases kept out of development. Checked the automatic scoring against eight specialist doctors reviewing the same 50 cases.
  • –Introduced a separate test of whether AI follows treatment guidelines: every system built around the guidelines did better than a model trained on past decisions, even though that model agreed with doctors in 99.2% of cases.

MD Thesis (Dr. med.)

Apr 2025 – present

Dept. of Neurology, University Hospital Dresden

  • –Built a model that predicts how Parkinson’s progresses from 17 routine clinical scores in 409 patients, designed to say when it is unsure instead of guessing. Checked its predictions against outcomes in a later patient group.

AI for Pancreatic Diagnosis

Dec 2025 – present

DKFZ and University Hospital Heidelberg

  • –Developed AI that tells pancreatic cancer, inflammation and normal tissue apart in microscope images: 96.8% balanced accuracy on 475 tissue slides, always tested on patients the model had not seen.

Student AI Researcher

Apr 2024 – Nov 2024

Kather Lab (EKFZ / TU Dresden)

  • –Used AI models that read DNA sequences to tell 19 cancer types apart, reaching 0.94 AUROC and 55.0% accuracy. Improved one model’s accuracy by almost 10%.
