Current Research

The Edgell lab at York University investigates human cardiovascular and autonomic function and will determine mechanisms behind the prevalence and lethality of cardiovascular disease in women to use this information to find potential avenues of treatment.

In particular, the lab will focus on 1) autonomic, cardiovascular, and respiratory responses to physiological stressors and the changes in those responses due to sex and/or female sex hormones, 2) investigating the symptoms of postural orthostatic tachycardia syndrome (POTS) throughout the menstrual cycle, and 3) investigating cardiovascular and autonomic function in ME/CFS and long COVID. 

We are also embarking on important research with the Toronto Rumsey Centre and Sunnybrook hospital investigating cardiac rehabilitation in male and female Type 2 Diabetes patients.
