Research Interests

Antibiotic resistance is a growing threat to human health. Bacteria that live in the human gut are an important reservoir of antibiotic resistance genes, and can potentially exchange those resistance genes with pathogens that cause human disease. Why some human gut-associated microbial communities harbor clinically important antibiotic resistance genes but others do not is poorly understood. Because infancy and early childhood represent critical periods for the development of the microbial community in the human gut, we hypothesize that this is also a critical time for antibiotic resistance genes to be established in human gut-associated microbial communities. In the laboratory of Gautam Dantas, Ph.D. (, I am currently studying the impact of various early childhood exposures on the developing cohort of antibiotic resistance genes in host-associated microbial communities.
