Dr. Khan is engaged in studies that focus on the molecular, cellular, and clinical features of human genetic diseases such as xeroderma pigmentosum, a cancer-prone recessive disease, and trichothiodystrophy, a multi-system disorder. The aim is to define the molecular defects associated with these diseases. These studies have revealed the significance of DNA repair in protection against cancer, neurological abnormalities and developmental defects. A more in-depth understanding of the pathophysiology of these diseases may lead to new strategies for therapeutic intervention of these diseases in affected patients as well as in the general population.
