Fully-funded postdoctoral positions are available to study regulation and inhibition of microbial metabolism in Staphylococcus aureus and/or Plasmodium falciparum (malaria parasites). Interested parties should contact Dr. John at [email protected].

The John Lab aims to discover new therapies and diagnostics for pediatric infections. Funded by the National Institutes of Health and the Burroughs Welcome Fund, our collaborative and interdisciplinary studies combine genetic, biochemical, and metabolic profiling techniques. We seek to advance our understanding of the fundamental biology and regulation of metabolism in human pathogens, such as malaria parasites, and translate these findings into improved clinical outcomes for children with infection.
