Report summary

The 2015-2017 picture for University of California, Irvine Department of Physics and Astronomy is a 39-PI network with 19 internal PI collaborations. The main research signal is Physics and Astronomy as the leading field (46% of slots across 29 PIs; 29 labels), Nuclear and High Energy Physics as the leading subfield (21% of slots across 16 PIs; 16 labels), and Astrophysics and Cosmic Phenomena as the leading topic (8% of slots across 9 PIs; 9 labels). That is a thin collaboration pattern, useful for spotting individual pairs but less persuasive as a broad departmental network. The leading PI names are Xiaoqing Pan (16.4 weighted works; Electronic and Structural Properties of Oxides, Ferroelectric and Piezoelectric Materials). The clearest collaboration lines are Zuzanna S. Siwy and Preston Hinkle (11 shared works, weight 6); Ruqian Wu and W. Ho (7 shared works, weight 3.9). The leading breakdown groups are group 1 with 5 PIs, 4 internal connections, weight 6.3, around Materials Chemistry, Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, led by Xiaoqing Pan, Ruqian Wu, Clare C. Yu; group 2 with 5 PIs, 5 internal connections, weight 8.8, around Biomedical Engineering, Electrical and Electronic Engineering, Materials Chemistry, led by Zuzanna S. Siwy, Reginald M. Penner, Preston Hinkle.
