KK Cheng (郑家强) has been Professor at the University of Birmingham since 1995. His main interests are in the epidemiology, prevention and control of important non-communicable diseases, and the development of primary care in China.

During the COVID-19 pandemic, KK was among the first researchers in western countries who advocated the importance of mask wearing in the community to control the pandemic (reference 4 below - published in The Lancet) on 2 March 2020. He questioned the guidance of the WHO on masks (reference 7) in the BMJ on 11 March and published a Comment summarising the importance of masks in The Lancet on 16 April, which have informed the debate on the issue.
