I am a virologist and Lecturer in Global Health at St George’s University of London, where I also hold a Medical Research Foundation Fellowship. I have extensive experience with viruses of great importance for human health, including HIV-1, Ebolavirus and Poliovirus. In the academic context, I combine molecular and cellular biology approaches to elucidate fundamental steps of the virus life cycle and its interaction with the host. During the Ebola outbreak in West Africa, I gained invaluable experience first as team leader of a molecular diagnostics laboratory in rural Sierra Leone (2015), and then as Public Health England (PHE) in-country lead (2015-2016).
During the lockdown in early 2020, I led the establishment of SARS-CoV-2 research at the Institute for Infection and Immunity, St George’s University of London, where we have a dedicated containment laboratory (CL3) for both fundamental and translational virology. I make the most of the great collaborative environment at St George's and work closely with both academic and clinical academic colleagues.
I am honoured to hold a personal fellowship from he Medical Research Foundation to support my research on a major contributor to the global burden of food/water-borne diseases: hepatitis A virus (HAV). The public health burden of HAV is heaviest in low middle-income countries (LMIC) with intermediate seroprevalence: improvements in economic and sanitary conditions reduce childhood infections, but also result in accumulation of naïve adults when levels of circulating virus remain high. Paradoxically, adult-acquired infections present more severe pathology and carry a higher risk of fatal outcomes than in children.
Although WHO encourages all its member states to vaccinate against HAV, low availability and high costs of the current vaccine (inactivated virus) have proven insurmountable challenges. Therefore, my research focuses on generating a novel HAV vaccine, made by expressing the viral structural proteins in mammalian and plant systems, as valid and cheaper new standard.
HAV is not just a threat in LMIC: outbreaks linked to sexual intercourse, food suppliers and school canteens are becoming increasingly larger and more frequent in high-income countries, including the UK.
I am passionate about making virology and science accessible to the public and, in pandemic times, I feel strongly about helping the public make sense of it.
