My interests are diverse aspects of algae biology. I study different aspects of nutrient responses in diatoms. Another interest is responses to light in diatoms. We have studied transitions from darkness to light and from low to high light, responses to different light qualities and diel gene regulation. Finally, I participate on a genome sequencing project on the diatom Seminavis robusta.
