Donovan Family Professor of Computer Science
Abstract: How does the brain beget the mind? How do molecules, cells and synapses effect reasoning, intelligence, language, science? Despite dazzling progress in experimental neuroscience we do not seem to be making progress in the overarching question – the gap is huge and a completely new approach seems to be required. As Richard Axel recently put it: “We don’t have a logic for the transformation of neural activity into thought.”
What kind of formal system would qualify as this “logic”? I will sketch a possible answer.

Bio: Christos H. Papadimitriou is the Donovan Family Professor of Computer Science at Columbia University. Before joining Columbia in 2017, he was a professor at UC Berkeley for the previous 22 years, and before that he taught at Harvard, MIT, NTU Athens, Stanford, and UCSD. He has written five textbooks and many articles on algorithms and complexity, and their applications to optimization, databases, control, AI, robotics, economics and game theory, the Internet, evolution and the brain. He holds a PhD from Princeton (1976) and an honorary doctorate from Univ. de Paris Dauphine (2017), and seven other honorary doctorates. He is a member of the National Academy of Sciences of the US, the American Academy of Arts and Sciences, and the National Academy of Engineering, and he has received the Knuth prize, the Godel prize, and the von Neumann medal. He has also written three novels: “Turing”, “Logicomix” and his latest “Independence”.

Professor of Computer Science
Bio: Ran Raz is a professor of computer science at Princeton University. Raz received his B.Sc. in mathematics and physics (1987) and Ph.D. in mathematics (1992) from the Hebrew University of Jerusalem. After a post-doctoral fellowship at Princeton he joined the faculty at the Weizmann Institute of Science. He was a visiting professor at the Institute for Advanced Study and at Microsoft Research. Raz’s main research area is complexity theory, with a focus on proving lower bounds for computational models. More specifically, he is interested in Boolean and arithmetic circuit complexity, communication complexity, probabilistically checkable proofs, quantum computation and communication, and randomness and derandomization.
