Antibody-mediated therapy and prevention of infectious pathogens

Our Laboratory focuses on human immunology with a strong interest in the development of B lymphocytes and antibodies. In particular, we are interested in the antibody response to HIV-1 and other infectious pathogens. We aim to precisely understand the biology of humoral immunity and to use this knowledge to effectively prevent and treat infectious diseases. To this end, our laboratory works with a wide range of techniques in molecular immunology and conducts clinical trials that enable us to translate our findings into clinical applications. Our group is dedicated to provide an excellent work environment to train young scientists and for pursuing forefront and innovative research.
