We are pleased to host Dr Moritz Kraemer, who will be presenting his talk, “The effect of human mobility and population density on the spread of COVID-19.” Dr Kraemer is a Branco Weiss Research Fellow in the Department of Zoology at the University of Oxford and an Associate of the Oxford Martin Programme on Pandemic Genomics. His work addresses questions related to the spatial spread of infectious diseases. In January, Dr Kraemer began building a global line list database of confirmed COVID-19 cases, which has evolved into the Open COVID-19 Data Working Group, an initiative co-led by the University of Oxford, Harvard Medical School, Northeastern University, and the University of Washington. Using this data and other global datasets, Dr Kraemer is focused on modelling the impact of human mobility on the spread of COVID-19 and identifying how human mobility data and genomic data can inform when lockdowns can be lifted.
