Islam Mesabah

Also known as إسلام مصبح

Islam Mesabah is a computer scientist who builds language-model systems that generate code from API documentation and extract structured data from scanned documents. After earning a bachelor's degree at the German University in Cairo in 2021 and working there as a research and teaching assistant until 2022, they completed a master's degree at TU Kaiserslautern in 2024, releasing the CoderAPI model and dataset on Hugging Face. At the German Research Center for Artificial Intelligence (DFKI), which they joined in May 2023, they coauthored 2025 studies on narrative priming in multi-agent LLM games and on tree-based reasoning in vision-language models. In 2026, they released the AraReceipt dataset of 100 Arabic receipts and the GAIDA human-in-the-loop annotation system. Since December 2025, they are a PhD student in computer science at RPTU Kaiserslautern-Landau, studying language models for code generation and optimisation while continuing as a researcher at DFKI.

Timeline

  1. 2016–2022

    Computer science in Cairo

    They study Computer Science and Engineering at the German University in Cairo from 2016 to 2021, graduating with high honours with a thesis on subword-level language identification for Arabic–English intra-word code-switching. In 2021, they coauthor the paper "Language Identification of Intra-Word Code-Switching for Arabic–English" in the Elsevier journal Array with Caroline Sabty, Özlem Çetinoğlu and Slim Abdennadher. From September 2021 to June 2022, they work at the university as a research and teaching assistant for Database Systems and Concepts of Programming Languages, supervising four bachelor theses.

  2. 2022–2024

    Master's degree in Kaiserslautern

    In 2022, they begin an M.Sc. in Computer Science at TU Kaiserslautern (now RPTU). From August 2022 to May 2023, they work as a research assistant in the Machine Learning Group, evaluating the language models GPT-3, OPT and BLOOM on English text style transfer. Their master's thesis, supervised by Sebastian Vollmer and Sergey Redyuk, studies efficient code generation with large language models using API documentation and finishes in March 2024.

  3. May 2023

    Researcher at DFKI

    They join the German Research Center for Artificial Intelligence (DFKI) in Kaiserslautern in May 2023, within the Department of Data Science and its Applications led by Professor Sebastian Vollmer. Their research centers on large language models and on extracting and structuring key information from image documents. At RPTU, they also coordinate and teach the annual Engineering with Generative AI course.

  4. March 2024

    The CoderAPI model

    In March 2024, they release the CoderAPI model and dataset on Hugging Face, the artifacts of their master's thesis. CoderAPI fine-tunes Instruct CodeT5+ 16B and retrieves API documentation at generation time, so the model writes multi-line Python for seen and unseen libraries.

  5. May–October 2025

    The Power of Stories

    In May 2025, they coauthor the preprint "The Power of Stories: Narrative Priming Shapes How LLM Agents Collaborate and Compete" with Gerrit Großmann, Sebastian J. Vollmer and others. The study primes LLM agents with stories in networked public-goods games and finds that shared narratives raise cooperation and contributions. In October 2025, the work is presented at NETGCOOP 2025 in Bilbao and published in Springer's Lecture Notes in Computer Science.

  6. September 2025

    Tree-based reasoning in VLMs

    In September 2025, they coauthor the preprint "Decomposing Visual Classification: Assessing Tree-Based Reasoning in VLMs" with Sary Elmansoury, Sebastian J. Vollmer and others. The paper decomposes visual classification into interpretable decision-tree steps and evaluates it on GTSRB and CIFAR-10, where tree-based reasoning underperforms standard zero-shot prompting.

  7. August–October 2026

    GAIDA and the AraReceipt dataset

    In August 2026, they release the AraReceipt dataset of 100 manually annotated Arabic receipt images labeled with 25 key-information classes and the GAIDA annotation toolkit. In October 2026, they post the preprint "GAIDA: Generative AI for Human-in-the-Loop Document Annotation", which combines OCR, LLM pre-annotation and a human reviewer to cut annotation time by up to 80%.

  8. Since December 2025

    A PhD on automated research

    In December 2025, they start a PhD in Computer Science at RPTU Kaiserslautern-Landau on language models for code generation and optimisation towards automated scientific research, supervised by Sebastian Vollmer and Brian Moser. In September 2026, they supervise three student projects that build multi-agent systems able to work with legacy tools and APIs as an AI IT assistant for organisations, while continuing as a researcher at DFKI.

From the biography.

  1. Nonprofit roles are 2.3 times as common in AI safetyIncludes DFKI. We estimate where people focused on safety, alignment and evaluation work. Nonprofit roles appear for 25.1% of safety people with known affiliations, compared with 11.0% in other areas.
  2. The top 10 organizations employed 22% of people shaping AI in 2025: 51% of company researchers and 21% of university researchersIncludes DFKI. We estimate the share of people shaping AI who worked at the top 10 organizations each year from 1955 to 2025, comparing concentration across companies, universities, and institutes and labs.
  3. The United States employs an estimated 48% of people shaping AIIncludes DFKI. We estimate where the people shaping AI work today, how universities, companies and research institutes split across countries, and how country shares have changed since the 1960s.
  4. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes DFKI. 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.
