Report summary

For University of California, Berkeley Department of Chemistry in 2021-2023, the graph shows 75 visible PIs and 84 internal PI collaborations. The dominant subject mix is Chemistry as the leading field (18% of slots across 28 PIs; 28 labels), Materials Chemistry as the leading subfield (12% of slots across 21 PIs; 21 labels), and Spectroscopy and Quantum Chemical Studies as the leading topic (7% of slots across 15 PIs; 15 labels). That is a healthy pattern, with enough links to reveal several interpretable groups rather than one undifferentiated component. The top weighted PIs are Peidong Yang (39.5 weighted works; Perovskite Materials and Applications, CO2 Reduction Techniques and Catalysts); Martin Head‐Gordon (35.9 weighted works; Advanced Chemical Physics Studies, Spectroscopy and Quantum Chemical Studies). The most visible ties are Stephen R. Leone and Daniel M. Neumark (15 shared works, weight 8.3). The standout breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 28.2, around Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, Materials Chemistry, led by Martin Head‐Gordon, Teresa Head‐Gordon, Jeffrey R. Long; group 2 with 8 PIs, 8 internal connections, weight 14.2, around Materials Chemistry, Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, led by Peidong Yang, Graham R. Fleming, David T. Limmer.
