CURRENT AREAS OF INTEREST
 
•
 The broad area of research in my lab is “Structure-function studies of membrane-associated proteins and peptides”. At present we are working on pore-forming toxin, naturally occurring antimicrobial peptides, design of novel cell-selective antimicrobial peptides and K+ channel proteins. By synthesizing conserved segments from these proteins and peptides, we are trying to identify and characterize their important structural and functional elements. Our long-term goal is to design peptides/peptidomimetics of pharmacological importance.
