Report summary

The 2024-2026 picture for Columbia University Department of Computer Science is a 12-PI network with 0 internal PI collaborations. The research center of gravity is Computer Science as the leading field (41% of slots across 7 PIs; 7 labels), Information Systems as the leading subfield (12% of slots across 3 PIs; 3 labels), and Single-cell and spatial transcriptomics as the leading topic (6% of slots across 2 PIs; 2 labels). That is a weak collaboration signal, so the page is better read as a faculty inventory than as evidence of a connected department. The top weighted PIs are Yangruibo Ding (4.2 weighted works; Software Engineering Research, Service-Oriented Architecture and Web Services); Steven M. Bellovin (4.1 weighted works; Artificial Intelligence in Law, Ethics and Social Impacts of AI). No internal PI-to-PI collaboration edge is visible in this period. No multi-PI collaboration group is visible in this period, a concerning sign if the department expects a connected internal network.
