Brief Introduction

The human genome is under constant attack from endogenous metabolic byproducts and environmental factors that can alter the chemical structure and corrupt its encoded message. The accumulation of somatic damage is now considered a main cause of the cancers as well as aging process. To cope with these DNA damage, organisms evolved an intricate network of DNA damage repair pathways, each focusing on a different class of DNA lesion. Our research focuses upon understanding the mechanism of damaged DNA recognition and propagating cellular events of damaged DNA repair system at the level of atomic resolution.

Research topics

Damaged DNA / Repair / Mutagenesis
