Greta Guarda, PhD

Immune Mechanisms

Group Leader

Via Vela, 6
6500 Bellinzona, Switzerland


Greta Guarda studied Molecular Biology at the University of Zurich and performed her diploma work at the Swiss Federal Institute of Technology, Zurich. From 2004 to 2007, she carried out her PhD work on T cell-mediated immunity at the Institute for Research in Biomedicine (IRB), Bellinzona. In 2007, she joined as post-doctoral fellow the University of Lausanne, where she became senior lecturer in 2010. During these years, she focused her research on NOD-like receptors and inflammasome function. She established her independent research group in 2012 thanks to the award of a Swiss National Science Foundation professorship and a European Research Council starting grant in 2013. In March 2018, Greta Guarda joined the IRB as Group Leader. For her scientific contributions, she was awarded the “Premio Fondazione Dr. Ettore Balli 2018” and the “Pfizer Research Prize 2019”. Since 2016, she is member of the Federal Ethics Committee on Non-Human Biotechnology.
