### Molecular computation and construction

**Special Events**

Speaker: | Erik Winfree, Caltech |

Location: | 693 Kerr |

Start time: | Mon, Mar 14 2005, 3:10PM |

Some of the simplest Turing-universal models of computation appear as natural generalizations of biochemical processes that occur in cells. Finite chemical reaction networks are related to Register Machines; enzyme reactions acting on polymers can directly simulate Turing Machines; self-assembly can simulate cellular automata and more. Our increasing ability to design complex molecules and systems makes these models of computation increasingly of interest for nanotechnology and biological engineering, as well as for fundamental understanding of biological processes. This talk will focus particularly on molecular self-assembly and questions related to the complexity of morphogenesis problems in this framework.

[Note companion talk "Algorithmic self-assembly of DNA" at 11am March 15 in the Condensed Matter/Biophysics seminar.
