Report summary

The 2015-2026 picture for Columbia University Department of Finance is a 6-PI network with 0 internal PI collaborations. The main research signal is Economics, Econometrics and Finance as the leading field (50% of slots across 4 PIs; 4 labels), General Economics, Econometrics and Finance as the leading subfield (25% of slots across 4 PIs; 4 labels), and Global Financial Crisis and Policies as the leading topic (17% of slots across 3 PIs; 3 labels). That is a weak collaboration signal, so the page is better read as a faculty inventory than as evidence of a connected department. The leading PI names are Charles W. Calomiris (53.6 weighted works; Banking stability, regulation, efficiency, Economic Theory and Policy); Geert Bekaert (37.7 weighted works; Global Financial Crisis and Policies, Monetary Policy and Economic Impact). No internal PI-to-PI collaboration edge is visible in this period. No multi-PI collaboration group is visible in this period, a concerning sign if the department expects a connected internal network.
