​Dr Preethi Prajod

  • Postdoctoral fellow, National Dental Research Institute Singapore
  • Instructor, Duke-NUS Graduate Medical School


Dr Preethi Prajod obtained her doctorate in Oral Biology at the National University of Singapore. Following her doctoral studies, she joined as a postdoctoral fellow at NDRIS. Her research interest lies in understanding oral microbiome-systemic health connections using advanced molecular, sequencing and multi-omics technologies. She works on translating oral microbiological research towards patient care and development of preventive strategies for systemic diseases. Dr Preethi has published high impact papers in internationally recognised journals and has received awards from the International Association for Dental Research.
