Report summary

For University of California, Irvine Department of Physics and Astronomy in 2021-2023, the graph shows 34 visible PIs and 10 internal PI collaborations. The dominant subject mix is Physics and Astronomy as the leading field (46% of slots across 25 PIs; 25 labels), Nuclear and High Energy Physics as the leading subfield (21% of slots across 14 PIs; 14 labels), and Particle physics theoretical and experimental studies as the leading topic (9% of slots across 9 PIs; 9 labels). That looks relatively sparse, so claims about department-wide cohesion should be made carefully. The top weighted PIs are Huolin L. Xin (49.2 weighted works; Advancements in Battery Materials, Advanced Battery Materials and Technologies). The most visible ties are Xiaoqing Pan and Ruqian Wu (11 shared works, weight 6). The standout breakdown groups are group 1 with 4 PIs, 3 internal connections, weight 7.3, around Materials Chemistry, Electrical and Electronic Engineering, Renewable Energy, Sustainability and the Environment, led by Huolin L. Xin, Xiaoqing Pan, Ruqian Wu.
