Report summary

The 2015-2017 picture for Northwestern University Department of Physics and Astronomy is a 31-PI network with 8 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (48% of slots across 22 PIs; 22 labels), Atomic and Molecular Physics, and Optics as the leading subfield (16% of slots across 9 PIs; 9 labels), and Particle physics theoretical and experimental studies as the leading topic (6% of slots across 6 PIs; 6 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 Samuel I. Stupp (14.5 weighted works; Supramolecular Self-Assembly in Materials, RNA Interference and Gene Delivery). The strongest pairings are André de Gouvêa and Kevin J. Kelly (8 shared works, weight 3.5). The standout breakdown groups are group 1 with 5 PIs, 5 internal connections, weight 6.8, around Nuclear and High Energy Physics, Astronomy and Astrophysics, led by André de Gouvêa, Ian Low, Kevin J. Kelly.
