Areas of interest:  

We are focused on delineating the molecular mechanisms underlying the mutagenic and carcinogenic properties of certain environmental and endogenous carcinogens. These include polycyclic aromatic carcinogens, present in automobile exhaust, tobacco smoke and cooked foods, as well as reactive oxygen species and estrogen derivatives. These can cause reaction with DNA. This damaged DNA may initiate cancer by producing mutations during DNA replication. Our research centers on investigating replication and repair of the damaged DNA using computational approaches. We employ computer modeling, molecular mechanics and dynamics simulations and quantum mechanical calculations for structural and thermodynamic analyses, to connect structure and thermodynamics with biological function. We work in close collaboration with Professor Nicholas E. Geacintov of the NYU Chemistry Department who provides the experimental data that anchors our computational studies.
