Research Interests and Our Expertise:

  • Glycans in Host-Pathogen Interactions;

  • Bacterial AB toxins;

  • Salmonella Host Adaptation, Virulence & Persistence;

  • Antimicrobial Resistance;

  • Vaccines & Toxin Neutralizing Antibodies

Overview & Background:

The unifying themes of our ongoing research program are seeking to understand the underlying mechanisms that control the pathogenesis and disease associated with Salmonella, as well as developing control strategies for the bacteria or its associated disease. The main focus of the ongoing work is on the Salmonella A2B5 Toxins: Biology, Pathogenesis, and Neutralization, while the research program is continuously evolving based on the current public health demand associated with typhoid fever.

We use a multidisciplinary approach integrating bacterial genetics, biochemistry, glycobiology, cell biology, immunology, structural biology, and animal models to decipher the interactions between the host and (drug-resistant) bacterial pathogens. Our research would offer important insights into the development of much-needed innovative controlling strategies against Salmonella infections and its associated diseases, but also into the advancement of our understanding of bacterial AB toxin biology and host-pathogen interactions.

Our ongoing research is supported in part by grants from National Institutes of Health/NIAID.

We are always interested in recruiting talented and passionate members to the dynamic and collegial group. Please apply!
