Report summary

The 2018-2020 picture for Purdue University West Lafayette Department of Computer Science is a 20-PI network with 3 internal PI collaborations. The research center of gravity is Computer Science as the leading field (35% of slots across 12 PIs; 12 labels), Artificial Intelligence as the leading subfield (10% of slots across 5 PIs; 5 labels), and Complex Network Analysis Techniques as the leading topic (4% of slots across 2 PIs; 2 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 Walter Gautschi (42 weighted works; Mathematical functions and polynomials, Mathematical Inequalities and Applications). The strongest pairings are Walid G. Aref and Ahmed R. Mahmood (7 shared works, weight 5.7). The standout breakdown groups are group 1 with 2 PIs, 1 internal connections, weight 1.6, around Electrical and Electronic Engineering, Artificial Intelligence, Signal Processing, led by Elisa Bertino, Ninghui Li.
