Emma graduated with a BSc (Hons) in Exercise Science from Brighton University before completing an MSc in Exercise Science at the University of Toronto, Canada. She then went on to complete her PhD in Exercise Science with a specialisation in cardiovascular physiology at the University of Toronto, Canada (2013).  After completing her PhD, Emma undertook post-doctoral studies in the Clinical Cardiovascular Physiology Laboratory at the Toronto General Hospital, Canada.  Emma’s research focuses on the cardiovascular health of women, with emphasis on the independent and combined effects of estrogen deficiency and exercise training in premenopausal and postmenopausal women. 

In January 2016, she returned to the UK to take the post of Lecturer in Exercise Physiology at the University of ߲Ƶ, becoming Senior Lecturer in 2022.

Emma is a member of The American Physiological Society and The British Association of Sport and Exercise Sciences. 

Emma’s main research interests focus on sex hormones and their effects on cardiovascular health and sporting performance. Her work includes the effects of the menstrual cycle on athletic performance in female athletes, the interactions between exercise and loss of sex hormones on cardiovascular health in postmenopausal women, and the effects of gender affirming hormones on athletic performance in transwomen athletes.

Emma is currently undertaking research in the following areas:

  • The menstrual cycle and athletic performance
  • The amenorrheic athlete and cardiovascular health
  • Postmenopausal women, cardiovascular health, and the effects of exercise
  • Gender affirming hormone therapy and athletic performance in transwomen athletes.

Invited reviewer for: Applied Physiology Nutrition and Metabolism; European Journal of Applied Physiology; Physical Medicine and Rehabilitation; Journal of Human Hypertension; Endocrine; Physiology and Behavior; and Osteoporosis International.
