Dr Mariano Sigman was born in Argentina and grew up in Barcelona, Spain. He obtained a masters degree in physics at the University of Buenos Aires and a PhD in neuroscience at Rockefeller University. In 2006 he founded the Integrative Neuroscience Laboratory at the University of Buenos Aires, bringing together physicists, psychologists, biologists, engineers, educational and biotechnology scientists, linguists, mathematicians, artists and computer scientists. The group has wide interests in neuroscience and experimental psychology. Sigman’s lab projects seek to understand the construction of confidence, and the decision-making process. Sigman will talk to Kim about his new book The Secret Life of the Mind, exploring the inner workings of the human brain.
