Report summary

For University of California, Berkeley Department of Civil and Environmental Engineering in 2015-2026, the graph shows 113 visible PIs and 134 internal PI collaborations. The dominant subject mix is Engineering as the leading field (36% of slots across 76 PIs; 76 labels), Civil and Structural Engineering as the leading subfield (12% of slots across 33 PIs; 33 labels), and Seismic Performance and Analysis as the leading topic (3% of slots across 11 PIs; 11 labels). That is a healthy pattern, with enough links to reveal several interpretable groups rather than one undifferentiated component. The top weighted PIs are Shaofan Li (72.5 weighted works; Numerical methods in engineering, Geotechnical Engineering and Underground Structures). The most visible ties are Jiaqi Li and Paulo J.M. Monteiro (28 shared works, weight 19). The standout breakdown groups are group 1 with 10 PIs, 12 internal connections, weight 58.7, around Civil and Structural Engineering, Building and Construction, Health, Toxicology and Mutagenesis, led by Kara L. Nelson, Scott Moura, Jiaqi Li; group 2 with 10 PIs, 11 internal connections, weight 29.5, around Civil and Structural Engineering, Electrical and Electronic Engineering, Atomic and Molecular Physics, and Optics, led by Kenichi Soga, Shakhzod Takhirov, Khalid M. Mosalam.
