Dr Chen obtained his PhD from the University of Queensland Australia, where he investigated inflammasome signalling in neutrophils in the laboratory of Prof. Kate Schroder. Subsequently, with the support of a Marie Curie Fellowship and a Swiss Government Excellence Fellowship, he completed his postdoctoral training with Professor Petr Broz at the University of Lausanne , Switzerland, studying the regulation of gasdermin proteins during infection and cell death. Dr. Kaiwen Chen joined the Department of Microbiology and Immunology as an Assistant Professor in late 2020.
The Chen lab focuses on the molecular regulation of innate immunity and programmed cell death, including pyroptosis, apoptosis, and necroptosis. We aim to uncover how these cell death pathways are activated during infection and inflammation, and how they contribute to host defence. A key area of interest is understanding how microbial pathogens subvert or manipulate these processes to evade immune responses and promote their survival. By dissecting these host–pathogen interactions at the molecular level, we seek to reveal fundamental mechanisms of immune regulation and identify potential targets for therapeutic intervention in infectious and inflammatory diseases.
