Forskningsintressen

Studies of tubulin and microtubule-associated proteins isolated from higher and lower vertebrates. Of particular interest is the reason for cold-adaptation of microtubules in coldwater living animals. Of special interest are animal coloration and the cellular mechanisms of pigment transport in melanophores.
