Senior Lecturer in Biomedical Science

Biography

Sandra gained her BSc from the University of Leeds and her PhD from the University of Liverpool. She returned to Leeds for her first doctoral position, where her ongoing research into ageing and the heart began. This developed during her senior doctoral position, funded as principal investigator by the BHF, followed by a Lectureship in Physiology. Sandra was appointed to a Lectureship in Biomedical Science at Hull in 2007, and promoted to Senior Lecturer in 2016. She is also a member of the Centre for Cardiovascular and Metabolic Research at Hull York Medical School. Her research concerns the causes of cardiac dysfunction, particularly in association with ageing.

Sandra is a Fellow of The Physiological Society (awarded 2018) and additionally the Society's representative at the University of Hull https://www.physoc.org/.

In 2020 Sandra was elected as a Fellow of the American Heart Association (FAHA) via the Basic Cardiovascular Science committee, in recognition of my leadership, scientific and professional accomplishments.

Research

My research revolves around changes in whole heart and cellular function with increasing age, from the perspectives of normal physiology and pathophysiology. My particular area of study are the changes in ionic regulation with age leading to the predisposition to arrhythmias, and other disorders of excitation and contraction within the elderly heart. Primarily my research group have used proteomics to examine the associated changes in protein expression and regulatory systems responsible for producing the age-associated changes in phenotype, coupled with functional measurements using electrophysiology. Recent targeted proteins in the mammalian heart have been the gap junctional subunit connexin43, the differing isoforms of the voltage-gated sodium ion channels and voltage-gated calcium ion channels. Our studies have conclude the change in expression of these ion channels expressed in the age heart, leave the age heart in a state of imbalance and experience high frequency of arrhythmias. Furthermore, we are now using interventions to protect the heart as it ages from the onset of associated pathologies, ranging from the global (e.g. exercise interventions), to the specific pharmaceutical agents (e.g. directed manipulation of signaling pathways), leading a novel approach to reduce AF events, to ultimately become a therapeutic strategy to prevent and treat AF in the elderly who are often unfit for surgery.

Postgraduate research supervision

Dr Jones welcomes applicants with experience in mammalian physiology (at degree level) and specific knowledge of the heart. Applicants should understand how ion channels contribute and give rise to the normal action potential of the mammalian heart at a basic degree level, as her research focuses on cardiac dysfunction and how it arises (for example with ageing). The techniques used in the laboratory are proteomic, genomic and functional. At the time of appointment, specific projects will be offered in line with ongoing projects in the group.
