Judiciary and judicial behavior
I study judicial institutions, especially the STF, and how professional trajectories, appointments and institutional profiles help explain decisions and internal divisions within courts.

Political scientist, postdoctoral researcher in the Department of Political Science at USP and at INCT-Participa.
I hold a BA in Social Sciences and an MA and PhD in Political Science from the University of São Paulo, with a doctoral research period in the Department of Methodology at the London School of Economics. I was a postdoctoral researcher in the Department of Political Science at the Federal University of Pernambuco.
I am a professor and postdoctoral researcher at USP and INCT-Participa, as well as an affiliated professor at UFPE. I am also a member of JUDE (Judiciary and Democracy), a research group dedicated to the study of judicial institutions and their consequences for democracy.
I study political institutions, with an emphasis on the Judiciary and especially the Brazilian Federal Supreme Court (STF). I am also interested in the political behavior of institutional actors, in how ideological orientations structure preferences, decisions and coalitions, and in quantitative research methods. My research agenda combines institutional theory and quantitative analysis, with a focus on ideal point estimation and quantitative text analysis.

A study of the individual behavior of Brazilian Federal Supreme Court (STF) justices in constitutional review cases decided by the collegiate court. The dissertation uses ideal point estimation to map disagreements among justices and assess the role of presidential nomination, professional trajectories and other characteristics in the formation of alignments on the Court.
