Dr Ashton Faulkner is a Lecturer in Biomedical Sciences and pursues a research programme in cardiovascular molecular metabolism.

The overarching research aim of the Faulkner lab is to further our mechanistic understanding of how molecular sensors and modulators of metabolism regulate cellular function in different cell types of the cardiovascular system. Of particular interest is understanding the molecular control of fatty acid channelling within vascular cells and how this is modulated during the establishment of cardio-metabolic disease. The goal is to harness this knowledge in the design of novel therapeutic interventions to facilitate cardiovascular protection and repair.

Dr Ashton Faulkner teaches cardiovascular science to BVetMed students in the pre-clinical years (BVetMed 1; BVetMed 2; GAB). He also contributes to teaching on the BSc Biological sciences course and supervises final year BSc and MSci project students.

Dr Faulkner is the local Biochemical Society ambassador (3-year term), facilitating interaction between the society and college.

  • Comparative endothelial cell function

    Endothelial cells (ECs) line the inner surface of blood vessels throughout the body and are involved in controlling inflammation, blood clotting, blood pressure and the formation of new blood vessels. Little is known about EC function in horses, despite the importance of EC in many equine diseases, and the interest in the horse as a large animal model of human diseases. This work is focused on learning more about equine endothelial cells and the differences between human and equine endothelial cell function.
