Overview

Background

United Nations (UN) member states in 2015 agreed to 17 global Sustainable Development Goals (SDGs) to end poverty, protect the planet and ensure prosperity for all. Dr Deirdre Mikkelsen is a microbiologist and Senior Lecturer in Food Science at the School of Agriculture and Food Sustainability, where her teaching and research contribute to several UN SDGs, including:

  • Goal 2 – Zero Hunger
  • Goal 3 – Good Health and Well-being
  • Goal 4 – Quality Education
  • Goal 12 – Responsible Consumption and Production
  • Goal 13 – Climate Action
  • Goal 15 – Life on Land

Deirdre holds a B.Sc. (First Class Honours, 1999) and a PhD in Microbiology (2005), both from UQ. She has expertise in molecular microbial ecology, bioinformatics and fermentation microbiology. Her academic journey includes research roles at the Advanced Wastewater Management Centre (2005) and from 2006 at the Centre for Nutrition and Food Sciences (CNAFS), Queensland Alliance for Agriculture and Food Innovation (QAAFI), where she held Postdoctoral and Research Fellow positions. She joined her current School in 2019.

Research impacts

Research Interests

Deirdre’s research focuses on understanding how foods, diets, and nutrients influence the gut microbiota in humans and monogastric animal models. Her work integrates molecular microbial ecology and biopolymer science to explore:

  • The structure and function of plant cell walls in cereals and grasses
  • The fermentability of dietary fibres as potential prebiotics
  • Microbial interactions with dietary fibres using molecular techniques
  • The impact of dietary fibres on gut microbiota diversity and abundance

Research Impact

Deirdre’s research supports sustainable food systems and improved health outcomes by advancing knowledge of gut microbiota–diet interactions. Her work informs the development of functional foods and dietary strategies to promote gut health.

She has published 88 peer-reviewed articles, with an h-index of 30 and 3916 citations. Over 80% of her publications appear in Q1 journals. A highlight of her career is a 2020 publication in Nature Communications, co-authored with colleagues from CNAFS and KTH Sweden.
