Report summary

University of California, Los Angeles Department of Physics and Astronomy in 2018-2020 reads as a 43-PI network with 15 internal PI collaborations. The dominant subject mix is Physics and Astronomy as the leading field (49% of slots across 35 PIs; 35 labels), Astronomy and Astrophysics as the leading subfield (21% of slots across 18 PIs; 18 labels), and Solar and Space Plasma Dynamics as the leading topic (5% of slots across 6 PIs; 6 labels). That is of concern for a 43-PI roster; the strongest pairings may be carrying much of the visible collaboration. The leading PI names are C. T. Russell (27.6 weighted works; Ionosphere and magnetosphere dynamics, Solar and Space Plasma Dynamics). The most visible ties are C. T. Russell and R. J. Strangeway (62 shared works, weight 12.9). The leading breakdown groups are group 1 with 4 PIs, 4 internal connections, weight 8.6, around Computational Mechanics, Structural Biology, Nuclear and High Energy Physics, led by P. Musumeci, J. B. Rosenzweig, Seth Putterman.
