Jason Yu is a Principal Scientist and computational chemist with eight years of experience applying first-principles and data-driven methods to drug discovery and materials design. He leads ML- and physics-based modeling efforts at Amgen, bridging structure- and ligand-based design to accelerate projects across discovery and optimization stages. His academic work spans developing coupled-cluster methods for periodic systems, open-source implementations in PySCF, and de novo design tools for molecular spin qubits—skills that combine deep theory with practical software engineering. Jason has industrial experience building AI-driven cheminformatics platforms (e.g., DEL analysis and RNA-binding hit discovery at Biogen) and a track record of shipping research code that integrates into production workflows. Based in Pasadena, he pairs a PhD in computational chemistry with notable open-source contributions to a widely used quantum chemistry library, illustrating a rare blend of research rigor and impactful engineering.
