Dr Andrew MN Walker
I graduated from the University of Sheffield in 2009 with BMedSci (1st Class Hons) and MBChB degrees. I was awarded membership of the Royal College of Physicians of London in 2012, before joining the University of Leeds in 2013, initially with a British Heart Foundation Research Scholarship. I was funded through a British Heart Foundation Clinical Research Training Fellowship between 2014 and 2017, following which I was awarded a PhD for my research project titled: Exploring the Role of the Insulin and Insulin-Like Growth Factor Receptors in Vascular Regeneration and Aging.
Since 2017 I have been an NIHR Academic Clinical Fellow in Cardiology based in the Leeds Institute of Cardiovascular and Metabolic Medicine (LICAMM) and Bradford Royal Infirmary.
- Lecturer on MBChB, iBSc in Cardiovascular Medicine and Cardiac Physiology Programmes
- Personal Tutor for iBSc Cardiovascular Medicine
My research interests include preclinical work investigating the role of the Insulin and Insulin-Like Growth Factor receptors in vascular regeneration and ageing. I also conduct clinical research in the field of heart failure, with a particular interest in factors which influence the prognosis of patients with insulin resistance and diabetes.
