Report summary

University of Michigan–ann Arbor Department of Mathematics in 2018-2020 reads as a 57-PI network with 3 internal PI collaborations. The dominant subject mix is Mathematics as the leading field (46% of slots across 43 PIs; 43 labels), Geometry and Topology as the leading subfield (19% of slots across 28 PIs; 28 labels), and Algebraic Geometry and Number Theory as the leading topic (8% of slots across 13 PIs; 13 labels). That is of concern for a 57-PI roster; the strongest pairings may be carrying much of the visible collaboration. The leading PI names are Virginia R. Young (9.5 weighted works; Insurance, Mortality, Demography, Risk Management, Probability and Risk Models). The most visible ties are Andreas Blass and Yuri Gurevich (4 shared works, weight 4). The leading breakdown groups are group 1 with 3 PIs, 2 internal connections, weight 3.4, around Experimental and Cognitive Psychology, Endocrine and Autonomic Systems, Psychiatry and Mental health, led by Daniel B. Forger, Victoria Booth, Olivia Walch.
