Co-head of the team BIPID at the IAME laboratory at the Paris University/ Bichat Hospital. Specialized in viral dynamics and antiviral treatment, his research focuses on understanding the mechanisms of drug actions and optimizing drug efficacy, in chronic (HIV, HBV) and acute emerging viral infections (SARS-CoV-2, Ebola, Nipah). He develops conceptual mathematical models to characterize the interactions between the host organisms (human or animal), the pathogen and the drug.
The results of the ANRS EP47 VISCONTI (Viro-Immunological Sustained COntrol after Treatment Interruption) study provided proof of concept that a state of sustainable HIV remission may be induced in at least some people with HIV: the post-treatment controllers (PTC). Unlike natural controllers, PTCs presented a symptomatic primary HIV-1 infection with high viral load and low… Continue reading Viral dynamics of rebound and control following early treatment of HIV/SIV (NIH)
The VISCONTI study proposed that post-treatment control (PTC) of HIV infection might be favored by early antiretroviral treatment (ART) initiation. However, a formal demonstration has not been established and the underlying mechanisms leading to PTC remain elusive. The pVISCONTI program aims to assess, in standardized conditions, the impact of early versus late ART initiation on… Continue reading A Non-Human Primate Model For HIV Remission (pVISCONTI)
