Report summary

The 2018-2020 picture for Cornell University Department of Physics is a 24-PI network with 14 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (36% of slots across 16 PIs; 16 labels), Atomic and Molecular Physics, and Optics as the leading subfield (13% of slots across 7 PIs; 7 labels), and Particle physics theoretical and experimental studies as the leading topic (7% of slots across 5 PIs; 5 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The top weighted PIs are Gennady Shvets (25.7 weighted works; Metamaterials and Metasurfaces Applications, Plasmonic and Surface Plasmon Research). The strongest pairings are Paul L. McEuen and Itai Cohen (7 shared works, weight 3.9); David A. Muller and Sol M. Grüner (6 shared works, weight 3.3). The standout breakdown groups are group 1 with 10 PIs, 13 internal connections, weight 17.3, around Materials Chemistry, Mechanical Engineering, Biomedical Engineering, led by David A. Muller, Itai Cohen, Kin Fai Mak.
