 Research Interests:

  1. Discover novel motifs mediating protein-protein interactions (PPIs) through analysis of protein interaction networks. PPIs are reported in the literature to be regulated by linear motifs (LMs), which are short elements embedded witin large protein sequences (Petsalaki and Russel, Curr Opin Bitechnol, 2008). These short linear peptide sections are often present in disordered regions in eukaryotic proteins and are responsible for thousands of protein-protein interactions.

  2. Discover drug-drug and food-drug interactions and in addition identify single drugs to target multiple diseases with related molecular mechanism. Based on the literature survey, it was observed there is a risk for medication-related adverse events in people using more than five medications, despite individual drug safety is taken care of by federal policies. Besides drug-drug interactions, we would like to test the hypothesis that single drugs can be identified to be effective among multiple diseases which have common transcriptional control or pathway involvement.
