• Description:

  Dawn Bonnell is a Trustee Professor of Materials Science at the University of Pennsylvania and the Director of the Nano/Bio Interface Center. She received her PhD from the University of Michigan and was a Fulbright scholar to the Max-Planck-Institute in Stuttgart, Germany, after which she worked at IBM Thomas Watson Research Center. She has authored or coauthored over 190 papers, edited several books, including Scanning Probe Microscopy and Spectroscopy: theory, techniques, and applications. The research in the Bonnell group focuses on atomic processes at surfaces. The group is produced the first images of atoms on oxide surfaces, and is currently interested in perovskite surfaces. More recently her group developed a new paradigm for fabricating nanostructured devices, Ferroelectric Nanolithography, that exploits domain specific reactivity at ferroelectric domains. An important aspect of this research program has been the invention of new microscopies that reveal the behavior of extremely small structures.
