Summary
👤
Senior🎓
Top SchoolMateusz Maciejewski is a computational drug discovery leader and CEO of MatGen with 13 years of experience blending machine learning, bioinformatics, and cheminformatics to deliver hands-on analysis and technical execution for drug discovery programs. He previously led data science at Pfizer and Korro Bio, building in-house ML pipelines that integrated RNA‑seq, FACS, proteomics and EMR data to reveal targets, biomarkers, and disease fingerprints. A serial founder and former Novartis postdoc, he has translated academic research—spanning NMR, molecular dynamics and adverse event analytics—into products like DrugRev and production-ready platforms. His open-source contributions include extending PyMOL with numerical and visualization scripts (involving NumPy and cgo) to aid molecular analysis, reflecting a rare mix of deep biophysics expertise and practical software craftsmanship. Based in Cambridge, MA, he combines strategic leadership with hands-on technical delivery and a track record of turning complex multimodal data into actionable biology.
