My research

This is an overview of my research. I have categorized it to make it more accessible due to your curiosity. I will try to revise it as soon as new projects are published. 

My Thesis

My thesis was titeled “Physiological changes following swimming in cold water in triathlon and military operations: Temperaturephysiology and cold water swimming with wetsuit or drysuit”. I did my dissertation at Oslo University Hospital on 12 May 2022.
