Biography: 

Currently Involved in:
Microbial Pathogenesis: Ongoing projects include studying the role of surface polysaccharides in pathogenesis and immunity of Vibrio spp.; virulence of community-associated staphylococcus aureus in lung infections; and virulence factors in mycobacteria and acinetobacter.
Infection Control: Development of self-sterilizing devices; extended spectrum beta-lactamase resistance in Gram negative bacteria
Molecular Epidemiology: Ongoing projects include studying the phylogeography of the cholera seventh pandemic; molecular typing of enterococci, V. cholerae, pneumococci, methicillin-resistant staphylococcus aureus (MRSA) and other organisms; and diarrhea infections in the developing world.
Microbial Ecology: Ongoing projects include studying the environmental reservoirs of nontuberculous mycobacteria.
Microbial Genetics: Ongoing projects include studying the evolution of vibrio spp., bacillus, in addition to staphylococcus aureus genomes and pathogenicity islands.

Prior to joining the Department in 2007, Dr. Johnson was a member of the faculty at the Department of Pathology at the University of Maryland School of Medicine and the chief of clinical microbiology and molecular diagnostics for the Veterans Affairs Maryland Health Care System.

She has authored more than 60 original articles and two book chapters on the polysaccharides of vibrio cholerae and on bacterial antibiotic resistance.

Dr. Johnson earned her doctorate degree from the University of Maryland and performed her postdoctoral fellowship at the Center for Vaccine Development at the University of Maryland, Baltimore.
