Report summary

University of Michigan–ann Arbor Department of Microbiology and Immunology in 2018-2020 reads as a 46-PI network with 39 internal PI collaborations. The dominant subject mix is Biochemistry, Genetics and Molecular Biology as the leading field (36% of slots across 35 PIs; 35 labels), Molecular Biology as the leading subfield (19% of slots across 23 PIs; 23 labels), and Gut microbiota and health as the leading topic (6% of slots across 8 PIs; 8 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 Yongqun He (14.4 weighted works; vaccines and immunoinformatics approaches, Computational Drug Discovery Methods). The most visible ties are Katherine Gallagher and Bethany B. Moore (13 shared works, weight 7.2); Harry L. T. Mobley and Sara N. Smith (15 shared works, weight 6.5). The leading breakdown groups are group 1 with 9 PIs, 11 internal connections, weight 14.1, around Immunology, Molecular Biology, Infectious Diseases, led by Bethany B. Moore, Katherine Gallagher, Christiane E. Wobus; group 2 with 8 PIs, 8 internal connections, weight 13.8, around Epidemiology, Molecular Biology, Endocrinology, led by Vincent B. Young, Jennifer Meddings, Eric C. Martens.
