Hi, I’m Emanuel! 👋

I’m a passionate Mathematician & Data Scientist with a proven track record of crafting and deploying Statistical / Machine Learning Models. These range from high-dimensional Financial Risk Models to large-scale Learning-to-Rank Models, serving thousands hourly.

With a B.Sc. & M.Sc. in Mathematics from TUM, I’ve built a strong foundation in Statistics & ML. Following industry experience as a ML Practitioner, I’m now pursuing a PhD in Statistics, fusing statistical rigor with the flexibilty and scalibility of modern ML.

Beyond Data & Tech, I’m an enthusiast for hiking, food, travel, often sharing these experiences with my amazing girlfriend. Thriving on challenges and fueled by collaboration, I’m all about the journey from the beauty of math to impactful innovation, while having fun along the way! 🚀🌍
