DrSmitha Sukumar

Level 3 Supervisor

Faculty of Medicine and Health

Research projects & supervision summary

Smitha leads an active research program spanning oral microbial ecosystems, antimicrobial resistance, clinical outcomes, and health professions education. Her research is embedded in clinical and educational settings and is strongly translational, conducted in collaboration with clinicians, scientists and educators. She is an approved HDR supervisor and welcomes enquiries from prospective PhD and MPhil students.

Project themes

  • Oral microbiome and post‑operative recovery following major surgery
  • Antimicrobial resistance and the oral resistome
  • Translational microbiome research to inform antibiotic stewardship and clinical decision‑making
  • Clinical and health professions education research, including clinical reasoning and assessment (co‑supervision available)

Methods & skills

Students will gain experience in clinical and translational research design, oral microbiome and resistome analysis, sample collection and preparation for genomic sequencing, clinical data integration, mixed‑methods research (where appropriate), research translation, and academic development.

RESEARCH PROJECTS & ACTIVITIES

  • PROJECT

    Does the community of oral bacteria affect how well a person recovers after major surgery. By checking patients’ oral health and taking small samples of saliva, and plaque before and after their operation, the study uses advanced genetic testing to see whether bacteria are linked to infections or slower healing after surgery
  • PROJECT
    Metagenomics to Medication

    This study creates a profile of antibiotic resistance gene (resistome) in oral plaque from adult patients. Metadata collected from patients and clinicians provide more comprehensive understanding of what factors influence resistome composition while providing clinicians with meaningful insight into actions of antibiotics on the microbiome
