Report summary

The 2021-2023 picture for Columbia University Department of Computer Science is a 18-PI network with 4 internal PI collaborations. The research center of gravity is Computer Science as the leading field (42% of slots across 13 PIs; 13 labels), Artificial Intelligence as the leading subfield (12% of slots across 5 PIs; 5 labels), and Topic Modeling as the leading topic (7% of slots across 4 PIs; 4 labels). That is a thin collaboration pattern, useful for spotting individual pairs but less persuasive as a broad departmental network. The top weighted PIs are Lydia B. Chilton (6.7 weighted works; Software Engineering Research, Ethics and Social Impacts of AI). The strongest pairings are Lydia B. Chilton and Vivian Liu (7 shared works, weight 5.2). The standout breakdown groups are group 1 with 3 PIs, 3 internal connections, weight 4.3, around Computer Networks and Communications, Artificial Intelligence, Information Systems, led by Vikram Nitin, Baishakhi Ray, Gail E. Kaiser.
