Research interests:

My lab is engaged in the systematic design of several peptides (which are considered as “nano-indicators”) and determine its three-dimensional structure using NMR spectroscopy in combination with molecular dynamics (MD) simulation to correlate its structure with  respective function such as antimicrobial activity, or antifreeze peptide or inhibitors of fibrillation.
