Professor emeritus
Institutt for fysikk
Noregs
teknisk-naturvitskaplege universitet (NTNU)
[før 1996: Noregs tekniske høgskole (NTH), Universitetet i
Trondheim]
Fødd 1931 i Skudenes.
Eksamen frå NTH, Elektroteknisk avdeling, som "siv.ing.",
1957 og som "dr.techn." , 1972.
Aktiv i bølgjekraftforsking sidan 1973, då Kjell Budal (1933-1989) tok initiativ til slik forsking ved NTH. Tidlegare forskingsinteresser var elektromagnetisme, fysikalsk elektronikk, termonukleær fusjon og plasmafysikk.
