Interdisciplinary Expertise:
|
|
Materials
problems in macromolecular crystallography; studies of radiation
sensitivity of biological crystals to synchrotron x-rays; design of new
crystal holders made by lithography techniques (suitable for handling
ultra-small crystals). |

template-directed crystal nucleation (biomineralization); strain relaxation
(change in interatomic spacing) at organic-inorganic interfaces; aqueous
chemistry of monovalent and divalent ions and their interactions with
Langmuir monolayers |

Techniques:
Versed in multiple x-ray techniques: grazing incidence synchrotron x-ray
diffraction, x-ray reflectivity, and extended x-ray absorption fine structure
