Timeline

  1. 2021

    Co-founding LAION

    He is among the founders of LAION e.V., a German non-profit for open AI models and datasets, set up in 2021 after the group had worked as private individuals until mid-2021. In November 2021, he is one of the authors of LAION-400M, a public dataset of 400 million CLIP-filtered image-text pairs.

  2. 2022

    LAION-5B and a NeurIPS award

    In 2022, he is one of the authors of LAION-5B, an open dataset of 5.85 billion CLIP-filtered image-text pairs. The paper wins an Outstanding Paper award at NeurIPS 2022.

  3. 2023

    A Falling Walls breakthrough

    In 2023, he is named among the LAION team that wins the Falling Walls Science Breakthrough of the Year award in the Science & Innovation Management category. The team is recognized for widening access to advanced AI models, tools and datasets.

  4. 2024

    Dermatology research at TUM

    In 2024, he researches dermatology at the Technical University of Munich after studying medicine, and he trains there as a dermatology specialist.

  5. August 2024

    Multimodal AI in diagnostics

    In August 2024, he coauthors "Evaluating multimodal AI in medical diagnostics" in npj Digital Medicine, listing the Department of Dermatology and Allergy at TUM. The study tests multimodal models on NEJM Image Challenge questions: the Claude 3 family is the most accurate among the AI models, and collective human decision-making outperforms all of them.

  6. May 2025

    HistoGPT for dermatopathology

    In May 2025, he is among the authors of HistoGPT in Nature Communications, a vision language model that generates pathology reports from histology images. The model is trained on 15,129 whole slide images from 6705 dermatology patients, and his affiliation on the paper is the Department of Dermatology and Allergy at TUM.

  7. As of October 2026

    LAION lead and founder

    In March 2026, he adopts LAION's Gender Equality Plan with Christoph Schuhmann and Jenia Jitsev. As of October 2026, he is Community, Medical and Operational Lead and a founder at LAION, with a Technical University of Munich affiliation.

From the biography.

  1. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes Technical University of Munich. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  2. Google has the highest combined h-index among AI organizationsIncludes Technical University of Munich. We estimate that Google holds the highest combined h-index at 8,016, while universities account for 73% of the deduplicated total across AI organizations.
  3. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other universityIncludes Technical University of Munich. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other university. We compare doctorate and 5+ year employment links, career timing and current workplaces for 187 major-prize and 1,111 best-paper winners.
  4. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes Technical University of Munich. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
