Report summary

The 2018-2020 picture for Columbia University Department of Computer Science is a 24-PI network with 5 internal PI collaborations. The research center of gravity is Computer Science as the leading field (35% of slots across 14 PIs; 14 labels), Artificial Intelligence as the leading subfield (12% of slots across 6 PIs; 6 labels), and Advanced Graph Theory Research as the leading topic (4% of slots across 3 PIs; 3 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 Xi Chen (48.4 weighted works; Supercapacitor Materials and Fabrication, Advanced Sensor and Energy Harvesting Materials). The strongest pairings are Ramy Eskander and Smaranda Muresan (4 shared works, weight 3.1). The standout breakdown groups are group 1 with 3 PIs, 2 internal connections, weight 1.7, around Electrical and Electronic Engineering, Automotive Engineering, Biomedical Engineering, led by Mingoo Seok, Martha Kim, Y. Tsividis.
