Report summary

For Harvard University Department of Systems Biology in 2021-2023, the graph shows 28 visible PIs and 19 internal PI collaborations. The dominant subject mix is Biochemistry, Genetics and Molecular Biology as the leading field (41% of slots across 24 PIs; 24 labels), Molecular Biology as the leading subfield (30% of slots across 21 PIs; 21 labels), and Gene Regulatory Network Analysis as the leading topic (6% of slots across 5 PIs; 5 labels). The network looks reasonably well-rounded, with visible collaboration groups but not so much concentration that one field explains the whole department. The top weighted PIs are Ralph Weissleder (19 weighted works; Click Chemistry and Applications, Extracellular vesicles in disease); Peter K. Sorger (14.7 weighted works; Cell Image Analysis Techniques, Single-cell and spatial transcriptomics). The most visible ties are Peter K. Sorger and Sandro Santagata (24 shared works, weight 10.5). The standout breakdown groups are group 1 with 9 PIs, 8 internal connections, weight 15.7, around Molecular Biology, Biophysics, Oncology, led by Ralph Weissleder, Peter K. Sorger, Sandro Santagata; group 2 with 8 PIs, 8 internal connections, weight 6.4, around Molecular Biology, Genetics, Infectious Diseases, led by Michael Springer, Timothy J. Mitchison, Chris Sander.
