Report summary

The 2015-2026 picture for University of Pittsburgh Department of Physics and Astronomy is a 50-PI network with 26 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (44% of slots across 36 PIs; 36 labels), Atomic and Molecular Physics, and Optics as the leading subfield (15% of slots across 15 PIs; 15 labels), and Particle physics theoretical and experimental studies as the leading topic (7% of slots across 10 PIs; 10 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The top weighted PIs are Chandralekha Singh (33.1 weighted works; Science Education and Pedagogy, Innovative Teaching Methods); Tao Han (31.4 weighted works; Particle physics theoretical and experimental studies, Dark Matter and Cosmic Phenomena). The strongest pairings are D. Boyanovsky and Shuyang Cao (7 shared works, weight 6.5); Jin Zhao and Hrvoje Petek (12 shared works, weight 6.2). The standout breakdown groups are group 1 with 6 PIs, 6 internal connections, weight 10.1, around Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, Materials Chemistry, led by Jin Zhao, Hrvoje Petek, Sergey Frolov.
