Research Focus and Interests         

Pathogen and Toxin Detection:

  • Biosensor technologies including laser light scattering, mammalian cell-based, and fiber optic sensors for rapid and high throughput screening of live pathogens and toxins in food
  • Development of biorecognition including antibodies, receptors, ligands, and microbiological growth media  

​Host-Pathogen Interaction and Control Strategies Using Probiotics :

  • Understanding the molecular and cellular mechanism of  Listeria monocytogenes colonization and translocation through epithelial barrier during intestinal phase of infection
  • Prevention and control using bioengineered probiotic and antimicrobial peptide loaded biocompatible nano-carrier
