Gigapixel images. Natural language. Open code.

Sander Moonemans Sander Moonemans

I'm Sander, a PhD candidate at Radboudumc, building open-source vision-language models that help pathologists analyze whole-slide images and converse about them in natural language. I'm also researching multi-agent systems and foundation models for pathology.

Big believer in tea and sports, when I'm not stuck in a terminal.

Research & Publications

My research focuses on making AI assistants for pathologists: open, reproducible, and clinically useful. I develop vision-language models that can understand gigapixel whole-slide images and converse about them in natural language. I'm also researching multi-agent systems and foundation models for pathology.

Projects

All code, data, and models are publicly available, because medical AI research should be open.

ANTONI-Alpha

🤗

An open-source vision-language model for computational pathology that enables natural language interactions with whole-slide images. Outperforms MedGemma on organ identification (0.91 vs 0.48), neoplasm detection, and differential diagnosis. Trained on HISTAI-Instruct with 1.1M+ instruction-response pairs.

Local Brain

A local-first project management tool written in Go. Combines human CLI/TUI interfaces with AI agent access through 18 purpose-built MCP tools. Your thoughts stay on your machine. Compatible with Obsidian and other markdown editors.

Polysome

A domain-agnostic framework for generating synthetic instruction-tuning data at scale using LLMs. Supports DAG-based prompt chaining, multiple inference engines (vLLM, llama.cpp, HuggingFace), and distributed GPU processing.

MOSAIC

🤗

Vision-language models for melanoma histopathology. The code from my Master thesis project, which has been published at MICCAI 2025. Generates human-level pathology reports on common lesions. Trained on 42,512 whole-slide images paired with 19,645 pathology reports.
