Training Group(s):
Biomolecular Structure and Biophysics

Active Mentor - currently hosting PULSe students for laboratory rotations and recruiting PULSe students into the laboratory; serves on preliminary exam committees

Current Research Interests:

Research in my laboratory is focused on structures and functions of cancer-specific DNA molecular targets and structure-based rational drug design. Particularly, we work on G-quadruplex (G4) DNA secondary structures formed in human oncogene promoters and human telomeres, which are attractive new molecular targets for cancer therapeutics. We seek to understand structure-function relationships of DNA G-quadruplexes, their protein interactions and drug targeting. In addition, we work on DNA-targeted anticancer drugs that inhibit transcription factors and topoisomerases. We use a combination of structural, biophysical, biochemical, molecular, and cellular methods in our research, in particular high-field NMR spectroscopy for biomolecular structural study.
