Report summary

The 2021-2023 picture for Columbia University Department of Biomedical Engineering is a 39-PI network with 29 internal PI collaborations. The research center of gravity is Medicine as the leading field (28% of slots across 22 PIs; 22 labels), Biomedical Engineering as the leading subfield (11% of slots across 11 PIs; 11 labels), and Neural dynamics and brain function as the leading topic (3% of slots across 3 PIs; 3 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The top weighted PIs are Gordana Vunjak‐Novakovic (24.8 weighted works; 3D Printing in Biomedical Research, Pluripotent Stem Cells Research). The strongest pairings are Gerard A. Ateshian and Clark T. Hung (10 shared works, weight 5.5). The standout breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 20.2, around Biomedical Engineering, Molecular Biology, Rheumatology, led by Gordana Vunjak‐Novakovic, Kam W. Leong, Gerard A. Ateshian.
