Report summary

University of California, Irvine Department of Chemistry in 2015-2026 reads as a 112-PI network with 177 internal PI collaborations. The research center of gravity is Chemistry as the leading field (17% of slots across 41 PIs; 41 labels), Molecular Biology as the leading subfield (9% of slots across 24 PIs; 24 labels), and Atmospheric chemistry and aerosols as the leading topic (5% of slots across 16 PIs; 16 labels). That is promising: collaboration is not just one large hairball, and the leading breakdown groups cover 22 PIs across distinct clusters. The most prominent PIs by weighted works are Shaul Mukamel (104 weighted works; Spectroscopy and Quantum Chemical Studies, Laser-Matter Interactions and Applications); William J. Evans (97.2 weighted works; Organometallic Complex Synthesis and Catalysis, Coordination Chemistry and Organometallics). The strongest pairings are William J. Evans and Filipp Furche (42 shared works, weight 21.8). The strongest breakdown groups are group 1 with 8 PIs, 8 internal connections, weight 48, around Atmospheric Science, Health, Toxicology and Mutagenesis, Insect Science, led by Manabu Shiraiwa, Sergey A. Nizkorodov, Barbara J. Finlayson‐Pitts.
