Welcome to my website! My name is Sebastian Ramirez Ruiz. I am a Doctoral Candidate and Research Associate at the Hertie School in Berlin. In the fall of 2025, I will be joining the European University Institute (EUI) as a Max Weber Postdoctoral Fellow. I am particularly interested in causal inference, opinion and preference formation, the use of research evidence in policy- and decision-making, #rstats, and most importantly, bicycles.
