Today's guest is Nina Luning Prak from the University of Pennsylvania. We talk a bit about the AIRR-Community but mostly about diagnosis of B or T cell malignancies and minimal residual disease evaluation and tracking of B cell clones in autoimmunity. Comments are welcome at the inbox of [email protected] or on social media under the hashtag #onAIRR.
