Curriculum Vitae

Jeg er utdannet i fiskeriteknologi og har jobbet med redskapsutvikling siden 2007. Har også en master i internasjonal fiskeri forvaltning. Selv om jeg har jobbet mest med trål og min PhD fra 2010 handlet om seleksjon i trålredskap, har jeg en del erfaring med andre redskap som line og teiner.
