Report summary

For Columbia University Department of Electrical Engineering in 2022-2026, the graph shows 28 visible PIs and 14 internal PI collaborations. The main research signal is Engineering as the leading field (29% of slots across 16 PIs; 16 labels), Electrical and Electronic Engineering as the leading subfield (13% of slots across 9 PIs; 9 labels), and Photonic and Optical Devices as the leading topic (5% of slots across 4 PIs; 4 labels). The network looks reasonably well-rounded, with visible collaboration groups but not so much concentration that one field explains the whole department. The most prominent PIs by weighted works are Keren Bergman (26.6 weighted works; Photonic and Optical Devices, Advanced Fiber Laser Technologies). The clearest collaboration lines are Michal Lipson and Alexander L. Gaeta (43 shared works, weight 20.1); Alexander L. Gaeta and Yun Zhao (22 shared works, weight 16.6). The strongest breakdown groups are group 1 with 4 PIs, 5 internal connections, weight 51.1, around Electrical and Electronic Engineering, Atomic and Molecular Physics, and Optics, Artificial Intelligence, led by Keren Bergman, Alexander L. Gaeta, Michal Lipson.
