Report summary

The 2015-2026 picture for University of California, Los Angeles Department of Physics and Astronomy is a 116-PI network with 85 internal PI collaborations. The main research signal is Physics and Astronomy as the leading field (55% of slots across 101 PIs; 101 labels), Astronomy and Astrophysics as the leading subfield (21% of slots across 49 PIs; 49 labels), and Particle physics theoretical and experimental studies as the leading topic (5% of slots across 17 PIs; 17 labels). The specialization is notable and potentially attractive, with the caveat that adjacent fields may have fewer local peers. The leading PI names are C. T. Russell (70.4 weighted works; Ionosphere and magnetosphere dynamics, Geomagnetism and Paleomagnetism Studies); Kang L. Wang (59.4 weighted works; Topological Materials and Phenomena, Advanced Condensed Matter Physics). The clearest collaboration lines are C. T. Russell and R. J. Strangeway (149 shared works, weight 25.3). The leading breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 27.1, around Atomic and Molecular Physics, and Optics, Condensed Matter Physics, Electrical and Electronic Engineering, led by Kang L. Wang, Yaroslav Tserkovnyak, P. Musumeci.
