William Samuel Bialek is a theoretical biophysicist and a professor at Princeton University and The Graduate Center, CUNY. Much of his work, which has ranged over a wide variety of theoretical problems at the interface of physics and biology, centers around whether various functions of living beings are optimal, and whether a precise quantification of their performance approaches limits set by basic physical principles. Best known among these is an influential series of studies applying the principles of information theory to the analysis of the neural encoding of information in the nervous system, showing that aspects of brain function can be described as essentially optimal strategies for adapting to the complex dynamics of the world, making the most of the available signals in the face of fundamental physical constraints and limitations. Bialek received his A.B. and Ph.D. degrees in Biophysics from the University of California, Berkeley. After postdoctoral appointments at the Rijksuniversiteit Groningen in the Netherlands and at the Kavli Institute for Theoretical Physics in Santa Barbara, he returned to Berkeley to join the faculty in 1986. In late 1990 he moved to the newly formed NEC Research Institute in Princeton. He is currently the John Archibald Wheeler/Battelle Professor in Physics at Princeton University, and a member of the multidisciplinary . In addition, he serves as Visiting Presidential Professor of Physics at The Graduate Center, CUNY. Bialek has made contributions to shaping the education of the next generation of scientists, such as organizing the Princeton Lectures on Biophysics, a series of workshops that provided many young physicists with an introduction to the challenges and opportunities at the interface with biology. The textbook he coauthored, Spikes: Exploring the neural code has also been similarly used by many young physics students as an introduction to neuroscience. He is currently involved in a major educational experiment at Princeton to create a truly integrated and mathematically sophisticated for first year college students. Most recently, he published Biophysics: Searching for Principles, a textbook based on his course for PhD students.
