Dr. Sidjabat's research areas are:

  • Molecular epidemiology and molecular characterisation of Antibiotic resistant bacteria
  • Bacterial Whole-Genome sequencing and bacterial proteome
  • Microbiology and microbiome of upper respiratory tract
  • research focus on microbiome, beneficial microbes and investigates mechanisms of plasmid-mediated antimicrobial resistance genes in Gram-negative pathogens. Probiotic discovery & development (visit our facebook site: https://www.facebook.com/probioticDD/)
