Our research group uses an integrated structural biology and biophysical approach combined with functional studies to understand the inhibition mechanisms of novel protein-RNA targets involved in human diseases and translate it to develop novel therapeutics.
We are interested in elucidating the molecular basis of the inhibition mechanism of novel drug targets. In collaboration with other groups in academia and industry, we are improving the potency and selectivity of inhibitors with biomedical applications.
