Professor Sarah Walker has been Principal Investigator of the ONS Covid Infection Survey since it started in April 2020. By regularly testing random samples of the UK population for infection and Covid antibodies, this has provided hugely valuable information as the Covid pandemic has progressed and has helped inform public health policy.
You can listen to her talk about the survey in the first episode of the new Statistically Speaking podcast by the Office of National Statistics (ONS), along with other people heavily involved in the survey.
