Tracy Hazen

Dr. Tracy Hazen is Assistant Professor in the Department of Microbiology and Immunology at the University of Maryland School of Medicine, with additional affiliation at the Institute for Genome Sciences. She holds a Ph.D. in Applied Biology from Georgia Institute of Technology, where she studied microbial ecology and Vibrio parahaemolyticus diversity.

Research employs comparative genomics and transcriptomics to investigate enteric pathogens (particularly E. coli-associated childhood diarrhea) and multidrug-resistant nosocomial pathogens. Current work focuses on antibiotic-resistant pathogen diversity and translational applications of sequencing-based microbial surveillance for outbreak detection in healthcare settings.

Key publications examine E. coli pathogenesis, virulence plasmids, multidrug resistance mechanisms, and genomic diversity of pathogens in clinical contexts. Research keywords include E. coli, Klebsiella, Acinetobacter, genomics, evolution, antibiotic resistance, and microbial surveillance.
