    • 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.
