Macroeconomist studying regional development, structural transformation, and how policy shapes economic change. Currently researching spatial Keynesian economics and demand spillovers at Colorado State University.
My primary research develops a spatial Keynesian framework examining how fiscal policy effects and demand spillovers propagate across regions. Using European NUTS2 regions during the Global Financial Crisis and Euro debt crisis, I explore how public sector shocks propagate across space and time to produce coordination failures that deepen economic contractions.
I examine how economies' industrial composition evolves and what role policy plays in steering this change. My work bridges theoretical frameworks with empirical analysis to understand production linkages, institutional capacity, and the mechanisms of economic development in both advanced and emerging economies.
Through demand-driven models and simulations, I explore how economies can navigate the energy transition while maintaining employment and growth. This research investigates the macroeconomic dynamics of capacity investment and the distributional implications of climate policy.
