Studying at Cambridge


Dr Dora Pereira


Dora Pereira holds an MEng (hons.) in Biochemical Engineering from the Technical University of Lisbon (Portugal) and a PhD in Gut Microbiome and Probiotics from the University of Reading (UK). Prior to her PhD she worked for 3 years as an R&D bioprocess engineer in the pharmaceutical industry. She joined the UK Medical Research Council Human Nutrition Unit in Cambridge in 2004. She was awarded an EU-funded 1-year Post-Doctoral Fellowship to study blood biomarkers of manganese exposure and later was appointed as MRC Investigator Scientist working on the development of a novel oral iron supplements and iron nutrition strategies to address iron deficiency anaemia. She was awarded the Royal Society of Chemistry Emerging Technology Award in 2014


As an MRC Senior Investigator Scientist, she was leading the ‘Oral Iron’ research theme until March 2016. 

In April 2016 she become a Research Group Leader at the University of Cambridge with independent funding to conduct a Phase II clinical trial with iron supplementation in young children, in collaboration with the MRC Unit The Gambia.  

Her research focuses on the risks and benefits of dietary and supplemental iron, particularly in what relates to gut health, infection and the gut microbiome, in populations living in the most deprived areas and at risk of enteric bacterial infection and gut parasites.
