Senior🎓
Top SchoolJoren Retel is a Senior Machine Learning Research Scientist at Pfizer with 11+ years of experience combining deep learning and computational biochemistry to accelerate drug discovery. Trained as a biochemist (PhD, summa cum laude) who solved challenging 3D folding problems, he has a rare blend of domain expertise in membrane protein structure determination and hands-on Python engineering. His work has progressed from academic breakthroughs—producing the first solid-state NMR model of a membrane protein in native lipids—to industry-scale ML method development at Bayer and Pfizer. Joren excels at extracting signal from ambiguous experimental data by designing algorithms that bridge noisy measurements and actionable molecular insight, and he maintains reproducible code on GitHub. Based in Berlin, he brings both rigor from structural biophysics and practical ML tooling to translational research teams.
