Overview


Microbial communities are present in almost all environments, and the full extent of their impact is largely unknown. Better understanding of how microorganisms interact with each other, their environment, and their hosts will provide immeasurable insights into all aspects of biomedical research.

My goal as Assistant Director in Duke Microbiome Center is to help facilitate efficient and effective study of these communities and their microbial constituents, and to develop novel techniques and approaches in order to enhance microbiome research across campus.
