Report summary

For University of Massachusetts Amherst Department of Chemistry in 2015-2026, the graph shows 70 visible PIs and 125 internal PI collaborations. The dominant subject mix is Biochemistry, Genetics and Molecular Biology as the leading field (24% of slots across 35 PIs; 35 labels), Molecular Biology as the leading subfield (20% of slots across 31 PIs; 31 labels), and Advanced biosensing and bioanalysis techniques as the leading topic (4% of slots across 8 PIs; 8 labels). That is a healthy pattern, with enough links to reveal several interpretable groups rather than one undifferentiated component. The top weighted PIs are Vincent M. Rotello (152.6 weighted works; Advanced biosensing and bioanalysis techniques, Advanced Nanomaterials in Catalysis). The most visible ties are S. Thayumanavan and Jingjing Gao (20 shared works, weight 12.8); Vincent M. Rotello and Richard W. Vachet (24 shared works, weight 12.8). The standout breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 90.5, around Molecular Biology, Biomaterials, Organic Chemistry, led by Vincent M. Rotello, S. Thayumanavan, Richard W. Vachet.
