Report summary

Columbia University Department of Chemistry in 2021-2023 reads as a 36-PI network with 54 internal PI collaborations. The dominant subject mix is Materials Science as the leading field (20% of slots across 17 PIs; 17 labels), Materials Chemistry as the leading subfield (16% of slots across 15 PIs; 15 labels), and Advanced Chemical Physics Studies as the leading topic (5% of slots across 5 PIs; 5 labels). That is promising: collaboration is not just one large hairball, and the leading breakdown groups cover 14 PIs across distinct clusters. The leading PI names are Tomislav Rovis (22.6 weighted works; Catalytic C–H Functionalization Methods, Radical Photochemical Reactions); Ruhong Zhou (21 weighted works; Graphene and Nanomaterials Applications, Graphene research and applications). The most visible ties are Colin Nuckolls and Latha Venkataraman (12 shared works, weight 6.6); Joonho Lee and David R. Reichman (12 shared works, weight 6.2). The leading breakdown groups are group 1 with 9 PIs, 11 internal connections, weight 37.3, around Materials Chemistry, Organic Chemistry, Electrical and Electronic Engineering, led by Colin Nuckolls, Xiaoyang Zhu, Latha Venkataraman.
