Summary
👤
Senior🎓
Top SchoolSacha Lewin is a Belgian PhD student in Data Science and Engineering at the University of Liège with a decade of hands-on software experience spanning deep learning, 3D vision, and backend systems. He began programming at 13, built and sold Minecraft add-ons to over 1,000 clients, and maintains open-source projects downloaded more than 300,000 times—showing both product-minded engineering and community impact. His research focuses on foundation models for complex scientific data, informed by award-winning master’s work and a published NeRFs paper from an industry internship. Comfortable across mathematics, physics, electronics and fluid mechanics, he brings multidisciplinary engineering rigor to ML problems. He contributes to projects like Nerfstudio (improving rendering and sampling) while still shipping practical plugins for gaming platforms. Colleagues know him as a pragmatic developer-educator who balances cutting-edge research with shipping usable software.
