     Xiaoyan Sun graduated from Zhejiang University of Technology, in Hangzhou, China. As an undergraduate student, she did research investigating the degradation of paclobutrazol introduced by microorganisms. Following the above project, she pursued research work in a bio-pharmaceutical chemistry project involving the biosynthesis of glutathione using yeast.
 
      After graduation, she worked at Zhejiang Chemicals Import and Exports Cooperation, China, as a junior research assistant. At the beginning of 2003, she went to Ann Arbor, starting doing research with Professor Al -Hashimi at Chemistry Department, University of Michigan as a research assistant. During that time, she was involved in a number of projects aimed at preparing and purifying RNA fragments from the genome of HIV-1 for NMR structural and dynamical studies.
 
     Currently, she is a third year graduate student, working on investigating the mechanism of HIV-1 DIS RNA isomerization using NMR. Her research is focused on characterizing the structure and dynamics of bulge contained by monomer DIS in the absence and presence of Mg2+; mapping the binding of NCp7 protein to monomer DIS; determining the relative orientation of DIS monomers in the C-2 symmetric kissing dimer via a palindromic loop sequence.
