Report summary

The 2015-2026 picture for New York University Department of Physics is a 54-PI network with 31 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (37% of slots across 34 PIs; 34 labels), Atomic and Molecular Physics, and Optics as the leading subfield (10% of slots across 13 PIs; 13 labels), and Astrophysical Phenomena and Observations as the leading topic (3% 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 Katepalli R. Sreenivasan (23.9 weighted works; Fluid Dynamics and Turbulent Flows, Combustion and flame dynamics); Alexander Y. Grosberg (22.3 weighted works; RNA Research and Splicing, Advanced Thermodynamics and Statistical Mechanics). The strongest pairings are Alexandra Zidovska and Jonah Eaton (8 shared works, weight 6.2). The standout breakdown groups are group 1 with 10 PIs, 12 internal connections, weight 13.1, around Atomic and Molecular Physics, and Optics, Materials Chemistry, Molecular Biology, led by Davood Shahrjerdi, Tim Byrnes, David G. Grier.
