Dr Anika Singanayagam is a Specialist Registrar in Infectious Diseases and General Internal Medicine, Clinical Fellow at Public Health England and Honorary Clinical Research Fellow at Imperial College. She completed a PhD (2020) with Professor Wendy Barclay (Imperial College), co-supervised by Professor Maria Zambon (Public Health England) funded by a Wellcome Trust Clinical Research Training Fellowship.

Anika graduated in Medicine from Oxford University in 2008. During this time she completed a BA (Hons) degree in Medical Sciences, in the theme of Infection and Immunity. As a postgraduate, she completed general medical training in London and subsequently entered specialty training as an Academic Clinical Fellow/SpR in Infectious Diseases and General Internal Medicine in 2012.

Her postgraduate research used in vitro and animal models to investigate biological properties of pandemic H1N1 influenza virus haemagglutinin that impact on human adaptation and airborne transmission, 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 - further details can be found here and here.

Since January 2020, Anika has worked at Public Health England where she has provided technical and scientific input on SARS-CoV-2, contributing to national public health policy. Her work on duration of infectiousness of COVID-19 can be found here.
