​
My research explores three themes in international economics: global value chains and firm production networks; firm productivity, innovation, and management practices; and financial frictions in international trade and investment.
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), funded by ERC Advanced Grant FIRMTECHNET.
