Research

My research agenda covers three broad themes: International trade, in particular its political economy and connection with foreign policy, the spatial dimension of international trade and migration, often in the context of the so-called gravity equation, and applied econometrics. My work is characterized by policy-relevant research questions that make use of state-of-the-art quantitative methods often involving big data, as well as devising and implementing econometric techniques to handle such types of data.
