Report summary

University of California, San Diego Department of Physics in 2015-2017 reads as a 33-PI network with 10 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (32% of slots across 21 PIs; 21 labels), Atomic and Molecular Physics, and Optics as the leading subfield (10% of slots across 8 PIs; 8 labels), and Particle physics theoretical and experimental studies as the leading topic (4% of slots across 4 PIs; 4 labels). That is of concern for a 33-PI roster; the strongest pairings may be carrying much of the visible collaboration. The most prominent PIs by weighted works are David Kleinfeld (11.8 weighted works; Neural dynamics and brain function, Functional Brain Connectivity Studies). The strongest pairings are D. N. Basov and M. M. Fogler (18 shared works, weight 9). The strongest breakdown groups are group 1 with 4 PIs, 4 internal connections, weight 11.8, around Biomedical Engineering, Electronic, Optical and Magnetic Materials, Civil and Structural Engineering, led by D. N. Basov, M. M. Fogler, Richard D. Averitt; group 2 with 4 PIs, 4 internal connections, weight 4.5, around Nuclear and High Energy Physics, Astronomy and Astrophysics, Artificial Intelligence, led by Benjaḿın Grinstein, Bartosz Fornal, Andrew Kobach.
