Report summary

The 2021-2023 picture for Columbia University Department of Electrical Engineering is a 22-PI network with 11 internal PI collaborations. The research center of gravity is Engineering as the leading field (32% of slots across 13 PIs; 13 labels), Electrical and Electronic Engineering as the leading subfield (16% of slots across 8 PIs; 8 labels), and Advanced Fiber Laser Technologies as the leading topic (5% 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 Alexander L. Gaeta (29.1 weighted works; Advanced Fiber Laser Technologies, Photonic and Optical Devices); Michal Lipson (26.3 weighted works; Photonic and Optical Devices, Advanced Fiber Laser Technologies). The strongest pairings are Michal Lipson and Alexander L. Gaeta (43 shared works, weight 19.1). The standout breakdown groups are group 1 with 8 PIs, 9 internal connections, weight 39.1, around Electrical and Electronic Engineering, Atomic and Molecular Physics, and Optics, Artificial Intelligence, led by Alexander L. Gaeta, Michal Lipson, Keren Bergman.
