Biography

Ice fish

BSc (Hons)

MSc

I am interested in heart performance in ectotherms, from cockles to crocodiles, during periods of oxygen deprivation and/or increased demand. During my time in the Shiels lab I investigated the relationship between whole-animal hypoxia tolerance and heart performance in European sea bass as part of a collaboration with Professor Guy Claireaux (Université de Bretagne Occidentale, France). I also carried out work on myocardial anoxia tolerance in common cockles and freshwater turtles, specifically regarding the role of the sarcoplasmic reticulum. I am now studying a PhD in the lab of Tobias Wang (Aarhus University, Denmark) investigating major evolutionary transitions in the vertebrate heart, particularly reptiles, and look forward to maintaining active collaborations with the Shiels group.
