Research interests

My research interest is to investigate structure-function relationship of various enzymes potentially useful for applications such as biocatalytic production of certain rare/valuable compounds and diagnostic bio-sensing. Also, structural studies on some drug target proteins such as reverse transcriptase are in progress for novel anti-viral drug development.
