Summary:

The Grad laboratory studies how pathogens evolve and spread through populations with the motivation of improving clinical and public health strategies for decreasing the burden of disease. To date, our efforts have focused on several pathogens, including Neisseria gonorrhoeae, respiratory syncytial virus, and E. coli. We aim to use a variety of methods, including genomics, epidemiological tools, and microbiology to define the dynamics of spread and characterize the genotypic and phenotypic diversity of the pathogens.
