Antonio Rangel is a professor of neuroscience and economics at Caltech. He received a Ph.D. in economics from Harvard University in 1998, and was an assistant professor of economics at Stanford from 1998 to 2006, as well as a research associate at the National Bureau of Economic Research. The Rangel Neuroeconomics Laboratory studies the computational and neurobiological basis of decision-making and the applications of this knowledge to economics, psychiatry and the development of ‘neurotechnologies’ designed to improve decision-making. The primary focus of Antonio’s lab is on understanding how the brain computes and compares values to make simple choices. Antonio and his team also investigate how the workings of the decision-making system change in more complex forms of choice, such as decisions involving self-control or altruism. He is a past president of the Society for Neuroeconomics.
