Biography

Dr Toshana Foster is an Assistant Professor in Molecular Virology and first established her research at the School as a Nottingham Research Fellow in 2018. Prior to this, Toshana obtained a Wellcome-funded PhD in the structural, biochemical and functional characterisation of hepatitis C virus (HCV) proteins from the University of Leeds in 2011. Following this, she moved to King's College London as a Postdoctoral Research Associate working on the molecular and cell biology of HIV-1 proteins. She investigated the role of innate immunity factors in restricting HIV-1 and their influence on HIV-1 envelope entry pathways. Now at Nottingham, Toshana's work has made significant contributions to understanding the molecular pathways and mechanisms that emerging arenaviruses exploit to establish infection. These zoonotic viruses pose an emerging threat to human health, and Toshana's group investigates how these viruses may circumvent host innate immune responses to cause disease and to cross the species barrier.
