I am a Visiting Professor at the Business School of Torcuato Di Tella University (2025-2026), an Independent Researcher at CONICET, and a member of the Neuroscience Laboratory. I teach undergraduate courses in the Bachelor’s program in Behavioral Science at Torcuato Di Tella University. I am also a Professor at the University of Buenos Aires (currently on leave), where I taught statistics and data science, and where I served as Director of the Instituto de Cálculo in 2024.
I study how people make decisions and form beliefs from limited evidence. I am interested in how confident they feel about those decisions and beliefs, and in how that confidence shapes what they do next: whether to act or keep exploring, whether to change their minds, and when to conclude that they have enough information to believe that something is true. I combine experiments on perception, learning and judgments of news with computational models that test explanations of how people make decisions and assess their accuracy. These experiments range from controlled laboratory tasks to online studies with large samples.
These questions first took shape in research on perceptual decisions and metacognition, the ability to evaluate one’s own thinking. My interest later led me to misinformation, where people must decide whether a political statement or a health headline is true, and where trust in institutions may shape who is misled.
I am also committed to teaching and public engagement. I have taught courses and workshops on statistical literacy for journalists, using real media examples and interactive exercises to help participants distinguish correlation from causation, recognize chance, and assess data quality in quantitative reporting.
I was trained as a physicist at the University of Buenos Aires (UBA), where I completed a PhD in 2009. During postdoctoral work with Marcelo Magnasco at The Rockefeller University (2009–2011) and Hakwan Lau at Columbia University (2011–2013), I moved into neuroscience and began to study conscious perception and metacognition. In 2014 I returned to Argentina as a researcher at the National Scientific and Technical Research Council (CONICET), the country’s main government agency for scientific and technological research. Based at the Instituto de Cálculo (IC), an applied mathematics and statistics research institute affiliated with UBA and CONICET, I built a research program in behavioral and cognitive science with my own doctoral students and collaborators. My work has appeared in journals spanning experimental psychology, neuroscience, cognition, and consciousness.
