Tracy H. Hazen

Tracy Hazen is an Assistant Professor in the Department of Microbiology and Immunology at the University of Maryland, Baltimore, with a primary appointment at the Institute for Genome Sciences. Her research focuses on genomic analysis of bacterial pathogens including Escherichia coli, Klebsiella, and Vibrio species to understand antibiotic resistance mechanisms and pathogen evolution in healthcare and environmental settings.

Her educational background includes a Ph.D. in Applied Biology specializing in Microbiology from the Georgia Institute of Technology, where she investigated microbial ecology and plasmid/phage contributions to bacterial genetic diversity in coastal environments. She completed postdoctoral training at the Institute for Genome Sciences before joining the faculty.

Dr. Hazen's research centers on microbial genomics, antibiotic resistance, and pathogen evolution, employing comparative genomics and transcriptomics to study enteric and nosocomial pathogens. She investigates virulence plasmids in E. coli and resistance mechanisms in Klebsiella, with emphasis on developing sequencing-based approaches for real-time pathogen tracking in hospitals to enhance infection control. Her work bridges clinical and environmental microbiology to address antimicrobial resistance challenges.

Analysis of her recent publications reveals consistent focus on genomic diversity of diarrheagenic E. coli and multidrug-resistant pathogens across global populations. She examines transmission dynamics in healthcare settings, plasmid-mediated resistance spread, and pathogen evolution in children from low-resource regions. Her studies frequently employ whole-genome sequencing to track outbreaks and characterize virulence factors in Shigella, Salmonella, and carbapenem-resistant Klebsiella.

The text does not specify graduate students advised by Dr. Hazen or detailed grant funding information. However, her extensive publication record in high-impact journals indicates active research support, likely from NIH and institutional sources, focused on genomic surveillance of antibiotic-resistant pathogens in clinical and community settings.

Dr. Hazen operates within the Institute for Genome Sciences at the University of Maryland, Baltimore, where she leads a research group applying cutting-edge genomic technologies to understand pathogen diversity and resistance mechanisms. Her collaborative work spans multiple international sites, particularly in sub-Saharan Africa and South Asia, addressing critical gaps in infectious disease surveillance and control.
