William Bialek

Who is William Bialek?

William Bialek is a theoretical biophysicist and a professor at Princeton University. 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 at 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 Lewis–Sigler Institute. In addition, he serves as Visiting Presidential Professor of Physics at the Graduate Center of the City University of New York.
