I am Federico Barrera, I live in Argentina, and I am a PhD student at the Torcuato Di Tella University. I have a Bachelor's degree in Physics and a Master of Science degree from the University of Buenos Aires. I have started working in Cognitive Neuroscience in 2015, by building a voice box to detect onset of speech in synchrony with an EEG machine. I later ventured into Computational Modeling for my Master’s thesis, identifying potential mechanisms of argumentation (and biases) that could lead to observable social collective states, like polarization. Currently, I am pursuing two main lines of research in Cognitive Psychology (as part of my PhD): improving the wisdom-of-crowds effect in factual questions where it often fails; and understanding why small groups of people can sometimes reach consensus on complex moral issues (but not always).
