Viktor Gradoux
PhD candidate in Economics, University of Lausanne (HEC)
I am a PhD candidate in Economics at the University of Lausanne, supervised by Kenza Benhima (UNIL) and Sylvia Kaufmann (Study Center Gerzensee). I am also a scientific collaborator at the Swiss Institute of Applied Economics (CREA), where I build macroeconomic forecasting models for Switzerland.
My research lies at the intersection of international macroeconomics and finance, energy and geoeconomics. I combine high-frequency and narrative identification with structural time-series methods to trace how financial and geopolitical shocks propagate through the global economy, and I work on the time-series toolkit itself.
Before my PhD, I was a research trainee at the European Central Bank and at the National Bank of Romania, and an economic consultant intern at Panthéon Recherche. I hold a dual master’s degree in Economics and Business Administration from HEC Lausanne and completed the Swiss Program for Beginning Doctoral Students in Economics at Study Center Gerzensee.
I am also the author of the textbook L’Économie en 60 graphiques (Dunod, 2nd edition), regularly among the top ten economics books for students in France.
