Cellular and functional heterogeneity
in host immunity
and microbial communities.

Our lab applies single-cell and computational genomics to two main questions: how a patient's immune system interacts with their breast tumor, and how function varies within human microbial communities such as the gut microbiome and fungal pathogens.
