Lecturer/Associate Professor in Dietetics (Physiology Specialist)

School of Health Professions (Faculty of Health & Human Sciences)


My professional journey began as a research assistant at the High Performance Centre of Barcelona in 2004. I combined several roles in teaching and research within the higher education until I began a PhD in Exercise Physiology and Nutrition in 2008 that was completed successfully in 2011 at the University of Barcelona. Then, I continued my academic career working as a Postdoctoral Research Fellowship within the Institute of Sport, Exercise and Active Living (ISEAL, Victoria University, Australia) until I joined the University of Plymouth in November 2014 to take a post as a Lecturer in Nutritional Physiology. 


Teaching Administration
Module Leader:
BSc in Dietetics (DIET111; DIET215; DIET222)
MSc in Human Nutrition (Sports Nutrition)

Nutrition and Exercise Physiology


Teaching interests

I teach undergraduate and postgraduate students on different aspects of physiology and nutrition. This relates to my interest in research on the impact of diet and exercise training regarding nitrate metabolism and cardiovascular health. 

Research interests

My current experiments within the Exercise, Nutrition and Health Laboratory are investigating the role of dietary nitrate ingestion by vegetarians and cardiovascular health. Currently, these experiments are funded by the Northcott Medical Foundation and the University of Plymouth. New experiments will also investigate the impact of exercise training on the nitrate/nitrite/nitric oxide pathway.
