Research synopsis

Research interests:

  • Molecular methods for microorganism detection and identification, with a focus on bacteria and fungi
  • Application of technology, such as MALDI-ToF Mass Spectrometry  to the clinical microbiology lab for microorganism identification and detection of biomarkers associated with antimicrobial resistance, and strain typing
  • Study of antifungal drug resistance trends, mechanisms of action and detection methods amongst clinical isolates of yeasts and molds
  • Examination of population level trends of invasive fungal infections
  • Application of NGS for diagnosis of infectious diseases
