We leverage genomics to transform our understanding of the human microbiome. Through metagenomic sequencing, we reveal diverse microbial communities in the gut, skin, and oral cavity, uncovering their impact on health, metabolism, immune function, and susceptibility to diseases like obesity and mental health disorders. Our genomic insights drive personalized interventions, such as probiotics and targeted antibiotics, aimed at enhancing health by modifying or restoring the microbiome.
