Tracy Hazen, Ph.D.

I joined the Rasko Lab in 2011 as a Postdoctoral Fellow, and was promoted to Research Associate in the Department of Microbiology and Immunology in September 2014.  Since joining the Rasko Lab I have worked primarily on the enteropathogenic E. coli (EPEC), but have also worked on projects investigating the genomic diversity of antibiotic resistance among E. coli, K. pneumoniae, and Acinetobacter spp.  I am especially interested in the diversity and role of plasmids in the development of virulence or antibiotic resistance among enteric and nosocomial pathogens.

For additional info about me you can visit my SOM faculty profile here.

When not doing research I like to spend time with my family, and I also like to paint:
