Ignacio Arana holds a BA in Journalism and Mass Communication from the Pontifical Catholic University of Chile (2002), a MA in Political Science from the University of Chile (2007), and a MA and a PhD in Political Science from the University of Pittsburgh (2015). His central line of research explores how the individual differences among presidents have an impact on relevant political phenomena, including institutional change and policy outcomes. His secondary line of research is the comparative study of institutions, with a focus on Latin America. He studies informal institutions, executive-legislative relations, judicial politics and elections.

My main present work is the book project How Leaders Erode Political Institutions: Presidential Personalities and Constitutional Change in Latin America. In this manuscript, I show that the personality traits of Latin American presidents explain which leaders attempt to change the constitution to increase their powers or extend their terms. I am also developing the World Leaders Database Project, a database that will contain biographical and psychometric information about national leaders that have governed nations around the world since 1970.
