Microbiome and Infections Research Group

The focus of my research is to explore the role of the microbiome in acute and chronic infections and its complex interactions with antimicrobial therapies. We aim to understand how microbiota can influence course of acute and chronic diseases and treatment responses. In parallel, we investigate the mechanisms underlying HIV and HTLV pathogenesis, with the ultimate goal of contributing to the development of curative strategies for HIV in clinical settings.

Our research

Our group has previously demonstrated that gut microbiota undergoes extensive changes during HIV infection, contributing to the chronic inflammation. We have also identified distinct microbiome signatures associated with antiretroviral therapy and shown, through in vitro experiments, that certain antiretrovirals exhibit antibacterial properties. Additionally, we have found that elite controllers — rare individuals capable of controlling HIV-1 infection without treatment — possess a gut microbiome like that of healthy individuals.

The primary goal of our research is to unravel the complex interplay between the microbiome and the immune system that underlies mechanisms of disease control and viral persistence. Our research is highly translational and patient-centered, applying cutting-edge multi-omics technologies to address clinically relevant questions.
