I am a postdoc at UFZ and iDiv in Leipzig, Germany.
I enjoy building open-source tools that help turn biodiversity observations into useful data and insights. My work ranges from scientific R packages for data processing and analysis to computer vision and AI-powered smartphone apps. I'm particularly interested in making biodiversity monitoring more accessible through affordable smartphones and on-device AI.

Work with me:
- Training, tuning and deploying AI models
- Turning raw image collections into analysis-ready datasets
- Statistical analysis with documented and reproducible workflows
📫 You can reach out to me via LinkedIn
Email is an option too (valentin [dot] stefan [at] ufz.de), but those inboxes get cluttered with a lot of spam & phishing nowadays, so LinkedIn is safer.
I manage pretty well in English, get by in French, am terrible at German, and am fluent in Romanian, though that last one doesn't come in particularly handy 😊
