Report summary

For University of Michigan–ann Arbor Department of Mathematics in 2015-2017, the graph shows 88 visible PIs and 15 internal PI collaborations. The dominant subject mix is Mathematics as the leading field (45% of slots across 66 PIs; 66 labels), Geometry and Topology as the leading subfield (18% of slots across 41 PIs; 41 labels), and Algebraic Geometry and Number Theory as the leading topic (5% of slots across 14 PIs; 14 labels). That looks relatively sparse, so claims about department-wide cohesion should be made carefully. The top weighted PIs are Virginia R. Young (10.6 weighted works; Insurance, Mortality, Demography, Risk Management, Insurance and Financial Risk Management); Indika Rajapakse (9.3 weighted works; Genomics and Chromatin Dynamics, Genomic variations and chromosomal abnormalities). The most visible ties are Charles R. Doering and Ian Tobasco (2 shared works, weight 2); Robert Krasny and Ling Xu (2 shared works, weight 2). The standout breakdown groups are group 1 with 4 PIs, 4 internal connections, weight 3.8, around Astronomy and Astrophysics, Applied Mathematics, Nuclear and High Energy Physics, led by Lydia Bieri, David Garfinkle, Sohrab Shahshahani.
