I study how the brain makes sense of what we see - and how we can use AI to understand it better. Currently finishing my PhD in Computational Cognitive Neuroscience at the Max Planck Institute in Leipzig.
Before academia, I worked as a data scientist building recommendation systems and ML pipelines. I like problems that sit at the intersection of neuroscience, machine learning, and building things that work.
What I Do
Science
Understanding how the brain processes visual information. I use deep learning models to study perception and develop methods to run more efficient neuroimaging experiments.
Engineering
Building things that work at scale. Recommendation systems at CHECK24, ML pipelines in production, and research tools like thingsvision that thousands of researchers use.
Selected Work
How to sample the world for understanding the visual system
Oral presentation on optimal stimulus selection for vision research.
Open Sourcethingsvision
Feature extraction library for computer vision models, used by researchers worldwide.
DatasetReLAION-2B Natural
Naturalness scores for 2.1B images + embeddings for ~500M natural photos. On Hugging Face.
