Report summary

Massachusetts Institute of Technology Department of Civil and Environmental Engineering in 2018-2020 reads as a 52-PI network with 28 internal PI collaborations. The dominant subject mix is Engineering as the leading field (25% of slots across 27 PIs; 27 labels), Civil and Structural Engineering as the leading subfield (8% of slots across 11 PIs; 11 labels), and Atmospheric chemistry and aerosols as the leading topic (3% of slots across 5 PIs; 5 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 Markus J. Buehler (47 weighted works; Silk-based biomaterials and applications, Machine Learning in Materials Science). The most visible ties are Jesse H. Kroll and Rachel E. O’Brien (5 shared works, weight 3.2). The leading breakdown groups are group 1 with 8 PIs, 8 internal connections, weight 9.5, around Biomaterials, Biomedical Engineering, Mechanics of Materials, led by Markus J. Buehler, Xuanhe Zhao, Benedetto Marelli; group 2 with 8 PIs, 9 internal connections, weight 13, around Atmospheric Science, Health, Toxicology and Mutagenesis, Global and Planetary Change, led by Jesse H. Kroll, Daniel J. Cziczo, Sam J. Silva.
