Ashlee M. Earl

Ashlee M. Earl is a research scientist and director of the Bacterial Genomics Group at the Broad Institute of MIT and Harvard, where she is an institute scientist. Within the Broad Institute’s Genomic Center for Infectious Diseases and Infectious Disease and Microbiome Program, Earl is working to understand the relationship between microbes and human health including how multi-drug resistant pathogens emerge and spread.

Earl coordinated much of the Broad’s research in the Human Microbiome Project and now leads a team of computational biologists to develop and utilize an array of ‘omics analytical approaches to dissect bacterial and host contributions to several infectious diseases. She has organized and led dozens of local and international collaborations to bring genomic approaches to the study of tuberculosis, urinary tract infections, and hospital-acquired infections caused by the enterococci and carbapenem-resistant Enterobacteriaceae.

Prior to joining the Broad Institute in 2009, Earl received her B.S. and Ph.D. in microbiology from Louisiana State University and postdoctoral training from Harvard Medical School with Dr. Roberto Kolter. In addition to expertise in microbiology, microbial genomics, genetics, metagenomics, and human microbiome research, Earl has experience in grant writing, scientific communication, teaching, and mentoring.
