Dr Tan is a Principal Investigator at the MRC Translational Immune Discovery Unit. His research focuses developing next-generation protein nanoparticle-based vaccines and antibody therapeutics against infectious diseases. He is particularly interested in understanding how the architecture of protein nanoparticle vaccines influences their immunogenicity, as well as investigating mucosal vaccine immunity to improve vaccine design against respiratory pathogens such as coronavirus. Dr Tan is part of an international consortium (Oxford-Caltech-CPI-Ingenza) funded by the Coalition of Epidemics Preparedness Innovations (CEPI) to develop novel a pan-sarbecovirus (SARS-like betacoronavirus) nanoparticle vaccine. He is also a Career Development Fellow at the Chinese-Academy of Medical Sciences-Oxford Institute, and a Fellow by Special Election at St Edmund Hall.
