Our group is interested in epigenetic regulation of somatic mutagenesis in normal and malignant B cells. Specifically, we aim to understand how alterations in the nuclear envelope influence B cell chromatin conformation, and what the epigenetic consequences of these alterations are.

Our group is interested in epigenetic regulation of somatic mutagenesis in normal and malignant B cells. Specifically, we aim to understand how alterations in the nuclear envelope influence B cell chromatin conformation, and what the epigenetic consequences of these alterations are.
At a systemic level, we are interested in how the lamina-associated chromatin domain (LAD) dynamics influence normal adaptive immunity, and whether dysregulation of this mechanism leads to autoimmunity and cancer.
From a translational perspective, we are aiming to develop novel therapeutic strategies to target nuclear lamina, establishing a new generation of treatment modalities of malignant lymphoma.
