Dr Anika Singanayagam is an Academic Clinical Lecturer in the Section of Adult Infectious Disease at Imperial College London. Her current work is in the laboratory of Prof Chris Chiu working on SARS-CoV-2 controlled human challenge models. She also actively collaborates on the ATACCC SARS-CoV-2 household contact study led by Prof Ajit Lalvani, with an interest in the virology and transmission of SARS-CoV-2

Anika graduated in Medicine (BM BCh BA(Hons)) from Oxford University in 2008. She completed general medical training in London and subsequently entered Infectious Diseases specialty training as an Academic Clinical Fellow in 2012.

Her PhD research (funded by a Wellcome Trust Clinical Research Training Fellowship) was in the laboratory of Prof Wendy Barclay, using in vitro and animal models to investigate how the stability of pandemic H1N1 influenza can impact on human adaptation and airborne transmission. The aim of this work is to facilitate understanding of how influenza viruses with pandemic potential emerge and spread.  More detail can be found here and here. Her doctoral work also involved investigating virological causes of reduced effectiveness of the nasally-administered live attenuated influenza vaccine.

Anika is also an Honorary Specialist Registrar in Infectious Diseases and General Internal Medicine at Imperial College Healthcare NHS Trust, and Honorary Clinical Fellow at UKHSA.  At UKHSA, she worked in the Virology Cell of the COVID-19 Incident Management Team from January 2020, providing technical and scientific input on virology, transmission and testing for SARS-CoV-2, contributing to national public health policy. Her UKHSA work on duration of infectiousness of COVID-19 can be found here.
