Albert Imsland

Professor

Professor II Albert K. Imsland (Mai 2010, ISI statistic 96, H-indeks 21) har lang forskningserfaring innen vekst og utvikling hos fisk, reproduksjon og tilpasning til miljøet, med fokus på marine arter. Sentral i Imslands forskning er miljømessig og arvelig styring av vekst og kjønnsmodning og hvordan disse prosessene påvirkes av indre og ytre faktorer. Imsland innehar også stilling som forskningsdirektør i akvakultur hos Akvaplan-niva i Tromsø. Via den stillingen, og sin bistilling ved UiB, bidrar Imsland til å gjøre forskningsfunn og kunnskap tilgjengelig for havbruksnæringen.
