Report summary

The 2024-2026 picture for Harvard University Department of Radiology is a 117-PI network with 114 internal PI collaborations. The main research signal is Medicine as the leading field (47% of slots across 101 PIs; 101 labels), Radiology, Nuclear Medicine and Imaging as the leading subfield (17% of slots across 50 PIs; 50 labels), and Advanced MRI Techniques and Applications as the leading topic (4% of slots across 14 PIs; 14 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The leading PI names are Shady Abohashem (14.6 weighted works; Cardiac Imaging and Diagnostics, Health disparities and outcomes); Ralph Weissleder (13.9 weighted works; Immune cells in cancer, Peptidase Inhibition and Analysis). The clearest collaboration lines are Shady Abohashem and Ahmed Tawakol (14 shared works, weight 6.3). The leading breakdown groups are group 1 with 10 PIs, 14 internal connections, weight 22.5, around Psychiatry and Mental health, Physiology, Cognitive Neuroscience, led by Changning Wang, Heidi I.L. Jacobs, Brian L. Edlow; group 2 with 10 PIs, 12 internal connections, weight 25.1, around Molecular Biology, Oncology, Pulmonary and Respiratory Medicine, led by Shady Abohashem, Avinash Kambadakone, Onofrio A. Catalano.
