Report summary

The 2015-2017 picture for Purdue University West Lafayette Department of Physics and Astronomy is a 33-PI network with 11 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (41% of slots across 24 PIs; 24 labels), Nuclear and High Energy Physics as the leading subfield (18% of slots across 13 PIs; 13 labels), and High-Energy Particle Collisions Research as the leading topic (7% of slots across 7 PIs; 7 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 Μαρία Πετροπούλου (13.8 weighted works; Gamma-ray bursts and supernovae, Pulsars and Gravitational Waves Research). The strongest pairings are Dimitrios Giannios and Μαρία Πετροπούλου (10 shared works, weight 6). The standout breakdown groups are group 1 with 4 PIs, 3 internal connections, weight 1.3, around Materials Chemistry, Electronic, Optical and Magnetic Materials, Atomic and Molecular Physics, and Optics, led by Yong P. Chen, Jiangping Hu, Chen Yang; group 2 with 4 PIs, 4 internal connections, weight 5, around Nuclear and High Energy Physics, Astronomy and Astrophysics, led by F. Wang, L. He, W. Xie.
