Report summary

The 2018-2020 picture for Purdue University West Lafayette Department of Chemistry is a 61-PI network with 52 internal PI collaborations. The research center of gravity is Chemistry as the leading field (21% of slots across 28 PIs; 28 labels), Molecular Biology as the leading subfield (14% of slots across 21 PIs; 21 labels), and Analytical Chemistry and Chromatography as the leading topic (4% of slots across 8 PIs; 8 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The top weighted PIs are Julia Laskin (1219.7 weighted works; Mass Spectrometry Techniques and Applications, Ion-surface interactions and analysis). The strongest pairings are Suzanne C. Bart and Mat­thias Zeller (16 shared works, weight 8.8). The standout breakdown groups are group 1 with 9 PIs, 8 internal connections, weight 21.1, around Organic Chemistry, Spectroscopy, Electrical and Electronic Engineering, led by Julia Laskin, Hilkka I. Kenttämaa, Suzanne C. Bart; group 2 with 9 PIs, 12 internal connections, weight 6.5, around Molecular Biology, Physical and Theoretical Chemistry, Education, led by Marcy H. Towns, W. Andy Tao, Jean Chmielewski.
