My lab studies the B cell repertoire by sequencing the DNA rearrangements that create antibodies. These DNA rearrangements are diverse; hence, when sufficiently similar rearrangements are observed, they are likely to derive from B cells that are clonally related. By studying the clonal landscape of the human B cell repertoire using next-generation sequencing (NGS), we hope to better understand how B cells mature and evolve in different organs in health and disease. We are also harnessing this knowledge to create clinical lab tests that identify and track B cell clones.
