Erika Schagatay - Science of Freediving #1
Erika Shagatay grew up in northern Sweden, far from the sea but eventually went to Lund University in southern Sweden to study biology, focusing on physiology and marine biology. She completed her PhD in 1996 on the human diving response.
She started her own research group in 2001 at Mid Sweden University where she has been a professor since 2007. The group has so far produced 6 theses focusing on freediving physiology.
She has also been very active developing freediving in Sweden and was part of the group that started competition freediving within the Swedish Sport Diving Federation.
