Report summary

University of Colorado Boulder Department of Mechanical Engineering in 2021-2023 reads as a 45-PI network with 43 internal PI collaborations. The dominant subject mix is Engineering as the leading field (35% of slots across 31 PIs; 31 labels), Biomedical Engineering as the leading subfield (13% of slots across 15 PIs; 15 labels), and Air Quality and Health Impacts as the leading topic (4% of slots across 6 PIs; 6 labels). Overall the pattern is balanced: there is enough structure to identify active groups, while the field mix still leaves room for multiple research identities. The leading PI names are Franck J. Vernerey (15.8 weighted works; Hydrogels: synthesis, properties, applications, Cellular Mechanics and Interactions). The most visible ties are Matheus I. N. Rosa and Massimo Ruzzene (20 shared works, weight 12.8). The leading breakdown groups are group 1 with 9 PIs, 8 internal connections, weight 21.2, around Biomedical Engineering, Mechanics of Materials, Mechanical Engineering, led by Mark A. Borden, Massimo Ruzzene, Rong Long; group 2 with 9 PIs, 8 internal connections, weight 8.6, around Biomedical Engineering, Pulmonary and Respiratory Medicine, Health, Toxicology and Mutagenesis, led by Gregory L. Whiting, Robert MacCurdy, Debanjan Mukherjee.
