| Biography | Mark Ratner is Morrison Professor of Chemistry and Professor of Materials Science and Engineering at NU. Ratner is interested in structure and function at the nanoscale, and the theory of fundamental chemical processes. He tries to bring together structure and function in molecular nanostructures, based on theoretical notions, on exemplary calculations, and (very importantly) on collaborations with experimentalists and other theorists, in the US and around the world. Some areas of interest are molecular electronics, electron transfer, self-assembly, nonlinear response in molecules, and theories of quantum dynamics. In the interstices, he spends as much time trout fishing as he possibly can. Ratner is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, the International Academy of Quantum Molecular Sciences and the Royal Danish Academy of Sciences. He has received the Langmuir Award from the American Chemical Society and the Feynman Award from the Foresight Institute. He also has also been a member of the Faculty Teaching Honor Roll at Northwestern eleven times, and has taught roughly five thousand students in General Chemistry in the last dozen years. He received his BA and PhD from Harvard and NU, respectively. |

Because DNA is a quasi-one-dimensional species, and because each base is a pi-type chromphore, it was long ago suggested that DNA could conduct electricity. This has become a widely investigated area, and remains of interest for fundamental science and for applications. We will discuss a very …
