    Collapse Overview 
    Collapse overview
    The main focus of my research is to understand the mechanisms by which RNAs mediate gene expression and regulation in both bacterial and eukaryotic systems. We are currently studying regulatory RNAs and RNA modifications using various single-molecule fluorescence microscopy and super-resolution imaging tools. my group is also interested in the development of new labeling, imaging and data analysis methods.
