Research & Clinical Interests

Research Interests:

Salmonellae translocated effectors which are delivered across the phagosome membrane and function to modify host processes by binding host GTPases, and acting as glycerol-cholesterol acyltransferases and ubiquitin ligases.
Bioinformatic analysis, DNA sequencing and phenotypic comparison of Shigella and Salmonella outbreak strains from diverse geographic locations including Central America and Africa and specifically the emergence of non-typhoidal Salmonella strains in Africa.
The environmental remodeling of the gram-negative bacterial envelope that occurs when bacteria infect host tissues and specifically the regulated alteration of glycerolphospholipids in the bacterial outer membrane by using a combination of bacterial genetics and mass spectrometry analysis of lipids.
Using NMR and crystallography to define structural mechanisms by which PhoQ responds to antimicrobial peptides and low pH and specifically testing the hypothesis that signal transduction involves the loss of structure on one side of the membrane with specific gain of structure on the other side of the membrane.
Identification of human genome polymorphisms that alter susceptibility to bacterial infection and diversity of human immune responses by using the human cellular genome wide association study (GWAS) platform using bacteria and the HapMap cell collection of normal human diversity.
How the bacterial second messenger di-c-GMP controls cellular processes and use of a FRET based biosensor for c-di-GMP to understand bacterial cellular function and diversity, and development of compounds that alter human interferon signaling by competing with mammalian molecules that bind cyclic nucleotides.
Human studies that involve analysis of the microbiota. The diseases analyzed using a metagenomic approach and DNA sequencing include inflammatory bowl disease and cystic fibrosis, as well as stool transplantation.
