Report summary

The 2024-2026 picture for California Institute of Technology Division of Biology and Biological Engineering is a 55-PI network with 30 internal PI collaborations. The research center of gravity is Biochemistry, Genetics and Molecular Biology as the leading field (40% of slots across 40 PIs; 40 labels), Molecular Biology as the leading subfield (26% of slots across 34 PIs; 34 labels), and Single-cell and spatial transcriptomics as the leading topic (3% of slots across 5 PIs; 5 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The top weighted PIs are Frances H. Arnold (12.7 weighted works; Enzyme Catalysis and Immobilization, Cyclopropane Reaction Mechanisms). The strongest pairings are Stephen L. Mayo and Henry A. Lester (3 shared works, weight 1.6). The standout breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 5.2, around Molecular Biology, Plant Science, Biophysics, led by Marianne Bronner‐Fraser, Dianne K. Newman, Changhuei Yang.
