- Translational Regulation in Immune Cells
Unravelling how mRNA translation governs the function of leukocytes and other key immune cells.
Inborn Errors of Immunity
Investigating genetic defects—ranging from disruptions in mRNA translation to other mutations—that underlie immune pathologies including infections, autoinflammation and autoimmunity
Molecular Mechanisms of Immune Dysregulation
Dissecting the pathways and cellular consequences of aberrant protein synthesis and its link to immune disorders.

Research Summary
Our lab is dedicated to understanding the molecular underpinnings of the human immune system. By focusing on the regulation of mRNA translation in leukocytes, we aim to illuminate how subtle disruptions in protein synthesis can lead to profound clinical consequences. Our work not only targets defects in the translational machinery but also encompasses a broader spectrum of genetic errors that compromise immune function. This research is critical to bridging the gap between fundamental molecular biology and clinical insights into immunodeficiency and auto-inflammatory conditions.
Our approach
We leverage primary human leukocytes as a model system, combining advanced molecular biology techniques with cutting-edge genomics and bioinformatics. Our multidisciplinary approach integrates clinical data and patient-derived samples to pinpoint the molecular drivers of immune dysfunction. This robust strategy is designed to pave the way for novel diagnostics and therapeutic interventions in patients with rare, severe immunological disorders.
