Report summary

Boston University Department of Mathematics and Statistics in 2015-2026 reads as a 59-PI network with 24 internal PI collaborations. The dominant subject mix is Mathematics as the leading field (32% of slots across 35 PIs; 35 labels), Geometry and Topology as the leading subfield (12% of slots across 18 PIs; 18 labels), and Algebraic Geometry and Number Theory as the leading topic (5% of slots across 9 PIs; 9 labels). That is of concern for a 59-PI roster; the strongest pairings may be carrying much of the visible collaboration. The leading PI names are Ramachandran S. Vasan (67.2 weighted works; Cardiovascular Function and Risk Factors, Cardiovascular Health and Risk Factors). The most visible ties are Ramachandran S. Vasan and Emelia J. Benjamin (97 shared works, weight 20.1). The leading breakdown groups are group 1 with 6 PIs, 10 internal connections, weight 56.1, around Cardiology and Cardiovascular Medicine, Surgery, Endocrinology, Diabetes and Metabolism, led by Ramachandran S. Vasan, Emelia J. Benjamin, Michelle T. Long.
