Dr Robert Dünner has been a senior scientific collaborator at the Swiss Tropical and Public Health Institute (Swiss TPH) since October 2020. In this BRCCH consortium, he is working on developing an agent-based model of the SARS-CoV-2 epidemic in Switzerland. This model will be combined with a machine-learning approach in order to investigate the optimal properties and delivery strategies of pharmaceutical interventions, including, but not limited to, vaccines. Dr Dünner has a PhD from ETH Zurich, where he developed an agent-based model of negative-frequency dependent host-parasite coevolution and used it to investigate the influence of hierarchical metapopulation structure on the maintenance of genetic diversity.
