Research Interests

We are searching for genes in the human genome that carry sequence variants, which are involved in resistance to infection and predispose to infectious diseases. Discovery of such genes can open new biological pathways and suggest new targets for intervention. We use methods of human genetics, including genome-wide association studies (GWAS) and exome sequencing, in vitro models of infection and methods of molecular biology to understand underlying biological mechanisms protecting from infection.
