Motivated by the intriguing functionality of gene regulatory networks we study chemical reactions (biological) circuits. We observe that those circuits are vastly different when compared to existing computing structures like logic circuits. In particular, the two strikingly different ingredients in biological circuits are feedback in memoryless computation and the stochastic behavior of devices in deterministic systems. Are these two biologically inspired concepts useful in improving the design of existing computing structures? I will provide a positive answer to this question and argue that progress in our understanding of biology depends on the development of new abstractions for reasoning about computation.


Jehoshua Bruck received both B.Sc. and M.Sc. degrees in Electrical Engineering from the Technion, Israel Institute of Technology, in 1982 and 1985 respectively, and a Ph.D. in Electrical Engineering from Stanford University in 1989. His research combines work on the design of distributed information systems and the theoretical study of biological circuits and systems. He has extensive industrial experience, including working with IBM Research for ten years where he participated in the design and implementation of the first IBM parallel computer. He was co-founder and Chairman of Rainfinity (acquired in 2005 by EMC), a spin-off company from Caltech that focused on software products for management of network information systems, and was the founding Director of the Caltech Information Science and Technology (IST) program.
