Hello, I'm Gereon.
I work on non-invasive brain-computer interfaces, currently as an Encode: AI for Science fellow and with the Parker Jones Neural Processing Lab in Oxford. Before that: Information Systems at TU Munich. Nice to meet you!
Stuff I'm doing:
People I work(ed) with:
Encode: AI for Science2026 – PresentFellowA one-year fellowship backed by Pillar VC and powered by ARIA, the UK's Advanced Research and Invention Agency. I joined in 2026.
Parker Jones Neural Processing Lab2024 – PresentVisiting ResearcherAfter initially joining remotely in October 2024, I joined the PNPL (pronounced 🍍) in Oxford in person as a visiting researcher between May 2025 and October 2025. Since then, we're back to collaborating remotely. Besides the LibriBrain competition, I am working on early-stage practical use cases for non-invasive speech-BCIs under the supervision of Oiwi Parker Jones.
Cyber-Human Lab2024 – 2025Visiting Postgraduate StudentUnder the supervision of Dr. Thomas Bohné and Dr. Sławomir Tadeja, I completed my Master's Thesis on the collaboration dynamics of industrial AR joint task execution at the CHL in Cambridge.
SelectCode2022 – 2025Working StudentFrom March 2022 until the end of my studies in 2025, I was a working student at SelectCode. After co-leading the SQlab Profiler team, I helped build meinGPT and scale it from 0 to 15,000 active users.
Manage and More2024 – 2025AlumnusFrom April 2024 to 2025, I was part of the 41st generation of Manage and More, the entrepreneurial scholarship offered by UnternehmerTUM.
Bavarian EliteAcademy2021 – 2023AlumnusIn 2021, I became part of the 23rd class of the leadership education program offered by the Bavarian EliteAcademy. In late 2023, I completed the program and joined the alumni network.
German Academic Scholarship Foundation2019 – 2025AlumnusFrom 2019 until the end of my Master's in 2025, I was a scholarship recipient of the German Academic Scholarship Foundation. The scholarship was renewed for my Master's in 2021.
TU Investment Club2019 – 2024Analyst & Head of ITThe TU Investment Club is a non-profit student organization dedicated to improving students financial literacy. I joined in 2019, and was Head of IT from 2022 to early 2024.

NeurIPS 2025 Data on the Brain & Mind WorkshoparXiv:2510.21038Non-invasive brain-computer interfaces (BCIs) are beginning to benefit from large, public benchmarks. However, current benchmarks target relatively simple, foundational tasks like Speech Detection and Phoneme Classification, while application-ready results on tasks like Brain-to-Text remain elusive. We propose Keyword Spotting (KWS) as a practically applicable, privacy-aware intermediate task. Using the deep 52-hour, within-subject LibriBrain corpus, we provide standardized train/validation/test splits for reproducible benchmarking, and adopt an evaluation protocol tailored to extreme class imbalance.

NeurIPS 2025 Datasets & Benchmarks TrackarXiv:2506.02098LibriBrain represents the largest single-subject MEG dataset to date for speech decoding, with over 50 hours of recordings -- 5× larger than the next comparable dataset and 50× larger than most. This unprecedented 'depth' of within-subject data enables exploration of neural representations at a scale previously unavailable with non-invasive methods. LibriBrain comprises high-quality MEG recordings together with detailed annotations from a single participant listening to naturalistic spoken English, covering nearly the full Sherlock Holmes canon. Designed to support advances in neural decoding, LibriBrain comes with a Python library for streamlined integration with deep learning frameworks, standard data splits for reproducibility, and baseline results for three foundational decoding tasks: speech detection, phoneme classification, and word classification.

NeurIPS 2025 Competition TrackarXiv:2506.10165The advance of speech decoding from non-invasive brain data holds the potential for profound societal impact. Among its most promising applications is the restoration of communication to paralysed individuals affected by speech deficits such as dysarthria, without the need for high-risk surgical interventions. The ultimate aim of the 2025 PNPL competition is to produce the conditions for an "ImageNet moment" or breakthrough in non-invasive neural decoding, by harnessing the collective power of the machine learning community.
