Report summary

Johns Hopkins University Department of Biostatistics in 2021-2023 reads as a 42-PI network with 47 internal PI collaborations. The research center of gravity is Medicine as the leading field (32% of slots across 27 PIs; 27 labels), Economics and Econometrics as the leading subfield (10% of slots across 11 PIs; 11 labels), and Health Systems, Economic Evaluations, Quality of Life as the leading topic (7% of slots across 9 PIs; 9 labels). That is promising: collaboration is not just one large hairball, and the leading breakdown groups cover 23 PIs across distinct clusters. The most prominent PIs by weighted works are Stephanie C. Hicks (36.2 weighted works; Neural Networks and Applications, Data Mining Algorithms and Applications). The strongest pairings are Karen Bandeen‐Roche and Ravi Varadhan (11 shared works, weight 5.6); Qian‐Li Xue and Karen Bandeen‐Roche (14 shared works, weight 4.5). The strongest breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 13.8, around Genetics, Molecular Biology, Epidemiology, led by Josef Coresh, Nilanjan Chatterjee, Rasika A. Mathias.
