Om Björn Thrandur Björnsson
Jag är professor emeritus i zoofysiologi med fiskendokrinologi och vattenbruk som expertområden.
Forskning
Jag arbetar inom forskargruppen FiskEndokrinologisla Laboratoriet (FEL-gruppen) där min fokus ligger på de endokrina system som styr aptit, energimetabolism och tillväxt hos fisk, speciellt laxfiskar, men också marina arter.
Jag är ledamot av styrgruppen för Swedish Mariculture Research Centre (SWEMARC) vid GU.
