William Bialek is the John Archibald Wheeler/Battelle Professor in Physics at Princeton University, where he is also a member of the multidisciplinary Lewis-Sigler Institute for Integrative Genomics, and is Visiting Presidential Professor of Physics at the Graduate Center of the City University of New York. He is the coauthor of "Spikes: Exploring the Neural Code".
William Bialek, Winner of the 2013 Swartz Prize for Theoretical and Computational Neuroscience, Society for Neuroscience "[T]he book goes beyond being a structured material for readers to learn about biophysics; it takes readers on an incredible journey in discovering fascinating ways in which biological phenomena can be viewed and studied. The technical adroitness and more importantly, the unique way of thinking about biological problems, in the reviewer's opinion, makes the book a must-read for any aspiring biophysicists."--Angie Ma, Contemporary Physics "[P]hysicists who are seeking an exciting intellectual path through the complexity of biology will deeply appreciate Bialek's clear vision of the big ideas and his expert guidance through their many applications."--Stephen J. Hagen, Physics Today "The book is well crafted, linking the historic work of the 'giants', e.g. Helmholtz with his seminal view of vision and hearing, with latest and trendy research, exemplified by the use of information theory in biology."--Robert Endres, Biological Physics Group Newsletter
