Mark Dean is an associate professor in the Department of Economics at Columbia University. He is also an associate director at the Columbia Experimental Laboratory in the Social Sciences (CELSS) and a member of the Cognition and Decision Lab.
Dean received his PhD in economics from New York University, where he was fortunate enough to be advised by neuroscientists as well as economists. Subsequently, Dean has worked largely in the field of behavioral economics, using tools from decision theory and experimental economics to devise and conduct robust tests of behavioral economic models. His most recent work is in the area of 'rational inattention,' which aims to understand how people allocate scarce cognitive resources when making economic choices.
