Report summary

The 2024-2026 picture for Columbia University Department of Biostatistics is a 16-PI network with 5 internal PI collaborations. The main research signal is Biochemistry, Genetics and Molecular Biology as the leading field (26% of slots across 8 PIs; 8 labels), Genetics as the leading subfield (15% of slots across 6 PIs; 6 labels), and Genetic Associations and Epidemiology as the leading topic (11% of slots across 5 PIs; 5 labels). That is a thin collaboration pattern, useful for spotting individual pairs but less persuasive as a broad departmental network. The leading PI names are Yian Gu (9.2 weighted works; Diet and metabolism studies, Nutritional Studies and Diet). The clearest collaboration lines are Iuliana Ionita‐Laza and Cue Hyunkyu Lee (1 shared works, weight 1). The leading breakdown groups are group 1 with 5 PIs, 4 internal connections, weight 1.3, around Molecular Biology, Physiology, Information Systems, led by Yian Gu, Linda Valeri, Jeff Goldsmith.
