My research focuses on HIV (human immunodeficiency virus), with two main axes: virus replication and virus evolution.
HIV replication. I have studied different steps of the HIV replication cycle, in particular: the process of HIV entry into target cells and virus tropism, proviral DNA integration, virus particle assembly, incorporation of the envelope glycoproteins into virions, virus pseudotyping. At present, research in my group focuses on the transmission of HIV from cell-to-cell and on interference with super-infection.
HIV evolution. I have worked for several years on the development of HIV resistance to antiretrovirals targeting different steps of the virus replication cycle. The aim was to elucidate the parameters driving the selection of specific drug-resistance mutations in treated patients. Among these, the impact of drug-resistance on virus fitness was a major issue of my research. At present, I explore the impact of type-I interferon on HIV replication and the viral strategies that lead to virus escape from interferons, both in vitro and in treated patients.
