Electron diffraction measurements of isolated, single sized clusters stored in ion traps is being applied to the study of
small (n ~10-50 atoms) metal clusters including Aun and Agn. These measurements are directed to better understand and exploit the
dependence of catalytic reactivity on cluster structure and temperature. Sensitive methods developed to measure laser-induced
fluorescence from <10 trapped ions are being applied to study the dynamics of DNA in gas phase. Temperature dependent measurements
demonstrate these methods will be useful to characterize conformational change in gas phase biomolecules. Sequential loss of electrons
from trapped DNA anions has been observed for the first time and experiments suggest DNA conformations may be a determining factor.

James Foley – (organic chemistry)
Our research interests center on understanding fundamental structure/function relationships pertaining to the
photophysics that govern the properties and behavior of organic dyes. We use this knowledge to develop improved chromophores
for use in biophysical, biological and medical applications such as single molecule detection, fluorescent reporting and
photodynamic therapy. Our approach encompasses nearly every aspect that is essential to such an undertaking including
computer-aided design, chemical synthesis and photophysical characterization of target dyes.
