Report summary

The 2018-2020 picture for Harvard University Department of Microbiology and Immunobiology is a 39-PI network with 32 internal PI collaborations. The research center of gravity is Medicine as the leading field (31% of slots across 22 PIs; 22 labels), Molecular Biology as the leading subfield (15% of slots across 14 PIs; 14 labels), and Immune Cell Function and Interaction as the leading topic (6% of slots across 7 PIs; 7 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The top weighted PIs are Suzanne Walker (13.3 weighted works; Glycosylation and Glycoproteins Research, Bacterial Genetics and Biotechnology). The strongest pairings are Christophe Benoıst and Diane Mathis (13 shared works, weight 6.3); Peter T. Sage and Arlene H. Sharpe (14 shared works, weight 5.5). The standout breakdown groups are group 1 with 10 PIs, 12 internal connections, weight 13.6, around Molecular Biology, Immunology, Endocrinology, led by Matthew K. Waldor, Diane Mathis, Philip J. Kranzusch.
