From single cells
to patients
immunity,
tumors,
microbiomes.

We apply single-cell and computational genomics to two connected problems: the crosstalk between a patient's immune system and their breast tumor, and the functional variation within human microbial communities — from gut microbiomes to fungal pathogens.
