About the person:

Lydia completed her BSc in Sport and Exercise Sciences at the University of Birmingham in 2014 and was awarded an MSc in Human and Applied Physiology, from Kings College London, in 2016. She then joined Bangor University, as a PhD researcher, in the autonomic cardiovascular laboratory. Lydia’s doctoral research examined the adaptation of the autonomic nervous system during chronic high-altitude hypoxia, with a specific focus on baroreflex control of blood pressure. She has taken part in research expeditions to the Himalaya and the Peruvian Andes, as part of the international research collaboration Global REACH, where she has collected data in lowland and high-altitude natives. Lydia has presented at several international conferences and scientific symposia and was awarded the Early Career Researcher Prize at the Physiological Society’s Extreme Environmental Physiology conference.

Research interests:

Lydia’s primary research interest is how the autonomic nervous system controls cardiovascular function, specifically the control of blood pressure by the arterial baroreflex mechanism. Lydia is interested in how arterial baroreflex function is altered during chronic hypoxic exposure, and its interation with other neural reflexes, including those originating from the peripheral oxygen sensors and pressure sensitive receptors in the pulmonary arteries. Lydia is also interested in the influence of sex on the regulation of blood pressure at high altitude, in both Lowland and highland natives.
