My research explores four themes in international economics: (i) global production networks and multinational activity; (ii) firm management and innovation; (iii) trade policy and disintegration; and (iv) financial frictions in trade and FDI.
In 2024-2029, I am pursuing a research program on Firm Network Technology (the activities and costs of network formation) and Technology in Firm Networks (the impact of firm links on innovation), under ERC/UKRI Advanced Grant FIRMTECHNET.
