Report summary

The Ohio State University Department of Materials Science and Engineering in 2015-2026 reads as a 116-PI network with 320 internal PI collaborations. The dominant subject mix is Engineering as the leading field (42% of slots across 90 PIs; 90 labels), Materials Chemistry as the leading subfield (18% of slots across 50 PIs; 50 labels), and Aluminum Alloy Microstructure Properties as the leading topic (3% of slots across 11 PIs; 11 labels). That is promising: collaboration is not just one large hairball, and the leading breakdown groups cover 24 PIs across distinct clusters. The leading PI names are Alan A. Luo (80.7 weighted works; Aluminum Alloys Composites Properties, Aluminum Alloy Microstructure Properties). The most visible ties are Hongping Zhao and Jinwoo Hwang (41 shared works, weight 20.3); Alan A. Luo and Jiashi Miao (33 shared works, weight 19.9). The leading breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 102.7, around Mechanical Engineering, Materials Chemistry, Surfaces, Coatings and Films, led by Yunzhi Wang, David W. McComb, Hamish L. Fraser; group 2 with 9 PIs, 9 internal connections, weight 57.9, around Materials Chemistry, Metals and Alloys, General Materials Science, led by G. S. Frankel, Adib J. Samin, Xiaolei Guo.
