Dr Nath’s PhD research was located in this field. She is continuing work on Oral Microbiome Transplantation (OMT) (transferring bacteria from a healthy donor to a recipient having oral disease) and using this technology for treating and preventing dental caries and periodontal disease, and using bioinformatics to create a “super donor assessment tool” for selection of healthy donors. She plans to start clinical trials using OMT 2025 and use this technology to improve the oral health of the Indigenous and socioeconomically disadvantaged populations.
Dr Nath is committed to understanding the lifestyle and environmental factors that could influence the oral microbiome. She is committed to improving oral health for the underprivileged population. Dr Nath has 10 years of experience in fieldwork and data collection. She has 5 years of experience engaging with Indigenous communities through culturally sensitive research practices.
