Biography summary

Dr Samantha Dawson is an Alfred Deakin Postdoctoral Research Fellow at the Food and Mood Centre (FAMC) and was recently awarded the Alfred Deakin Medal for the University’s best PhD thesis of the year. She leads the Perinatal Nutritional Psychiatry stream of research within the FAMC.

Samantha's work focuses on understanding diet-by-microbiome pathways impacting maternal and infant health, and developing, testing and implementing interventions to improve women’s diet before and during pregnancy.

She is one of our rising stars, who at a remarkably early stage in her career, has secured more than $1M in funding for her research stream, including a recent Medical Research Future Fund (MRFF) grant for the Bugs & Bumps trial.

Research groups

Food & Mood Centre, Deakin University

Institute for Mental and Physical Health and Clinical Translation, Deakin University

Early Life Epigenetics, Murdoch Childrens Research Institute

Projects

  • Leading a translational research topic focused on ‘increasing the proportion of pregnant women meeting the dietary guidelines’ within the Pregnancy Research and Translation Ecosystem, which is a platform for pregnancy research co-design with clinical stakeholders in southwest Victoria.
  • Principal investigator on the ‘Healthy Parents, Health Kids’ study, which was an RCT study trialling the efficacy of a face-to-face perinatal dietary intervention on improving maternal diet quality and altering the gut microbiota of mothers and children.
  • Led the co-design and development of the Bugs & Bumps smartphone app for pregnant women, which was underpinned by her HPHK prenatal dietary intervention. This project received Philanthropic funding form the Waterloo Foundation in the UK.
  • Principal investigator on the Bugs & Bumps RCT, which is a two-year trial testing the efficacy of the Bugs & Bumps program compared to the Australian Dietary Guideline advice, on improving maternal diet quality, altering the gut microbiome and inflammatory markers in mothers and infants, and influencing child emotional, cognitive and language outcomes over the first 18 months of life. As PI, Samantha secured funding from the MRFF and the Waterloo Foundation to conduct this trial.
