My profile
Biography
Senior Lecturer in Human Physiology in the Department of Life Sciences with pedagogic responsibilities to help support undergraduate and postgraduate teaching. Research interests are in integrative neural and metabolic control of cerebrovascular and cardiovascular systems investigating basic and translational research questions in healthy and diseased populations. Research fellow at Liverpool Centre for Cardiovascular Science (University of Liverpool and Liverpool Heart and Chest Hospital). I serve on Hypertension’s editorial board as an early career editorial fellow and peer review manuscripts for a number of scientific journals (Experimental Physiology, European Journal of Applied Physiology, Physiological Reports, Journal of Applied Physiology, American Journal of Physiology-Heart and Circulatory Physiology, EuroPace and others).
I am currently seeking highly motivated research students who are interested in studying basic and/or translational questions pertaining to cerebrovascular and/or cardiovascular control in humans. Prospective research students (MRes and PhD) are encouraged to directly contact me to discuss potential projects / opportunities.
