Dr Dunja Aksentijevic is a Reader at the William Harvey Research Institute, Queen Mary University of London. Dunja graduated from the University of Hull in 2004 with a BSc (Hons First Class) in Biomedical Science and was the recipient of the Faculty of Science Academic Scholarship. She was awarded the University of Hull Frederick Atkinson Prize Scholarship and NHS Renal Research Fund Fellowship for her doctoral studies to examine myocardial insulin resistance in chronic kidney disease. Immediately upon completion of her doctoral thesis in 2008, she joined the group of Prof Stefan Neubauer at the Radcliffe Department of Medicine, University of Oxford.
Her first postdoctoral position focused on investigating the therapeutic potential of modulating myocardial energetics in heart failure. In 2013, she moved to King’s College London, The Rayne Institute, St Thomas Hospital as the senior research fellow in the laboratory of Prof Michael Shattock to study impact of sodium modulation on heart metabolism. In 2017 Dunja was appointed Lecturer in Physiology/Biochemistry at the School of Biological and Chemical Sciences, Queen Mary University of London. In 2020, she joined William Harvey Research Institute (British Heart Foundation Accelerator Fellow) and in 2021 received her Wellcome Trust Career Development Fellowship.
Current roles include Programme Lead for MSc Clinical Drug Development, MSc Healthcare Research Methods, MRes Clinical Research, Academic Visitor University of Oxford, Honorary Research Fellow King’s College London.

Heart failure affects over 64 million people worldwide, with few effective treatments available, therefore it is an enormous global medical and economic burden. Defects in cardiac metabolism are a major cause of heart failure, but this area has not been intensively investigated. Therefore, cardiac metabolism is a promising, unexplored subject for the development of novel therapies.
My research aims to determine how metabolic remodelling contributes to the pathophysiology of heart failure and from this develop novel therapies targeting metabolism. Ongoing projects include:
- The role of chronic inflammation in cardiac metabolic dysfunction in type 2 diabetes (Wellcome Trust Career Re-Entry Fellowship)
- Identification of novel metabolic therapeutic strategies to treat HF including replenishment of metabolic intermediates and modification of mitochondrial substrate utilization
- Cellular mechanism of cardiac metabolic derangement during chronic kidney disease.
- Impact of the pregnancy conditions on cardiometabolic syndrome and heart failure in the offspring.
To investigate these areas, I have developed techniques which integrate physiology with NMR spectroscopy (23Na, 31P, 13C, 1H) that enable assessment of cardiac metabolism in situ. Furthermore, my recently awarded Wellcome Trust Fellowship (in partnership with AstraZeneca) will focus on heart failure due to chronic inflammation driven by systemic metabolic stress in type 2 diabetes.
