Presentation

Marine biologist who investigates how phytoplankton survives between blooms, focusing on dormancy and resting stages that can survive in sediments. I investigate how they survive by measuring nutrient exchange and assimilation on a single cell level, focusing on cyanobacteria, diatoms and heterotrophic bacteria that interacts with them. 

Research

I manly use stable isotopic tracers to measure carbon and nitrogen assimilation of individual cells, these cells are then analyzed using methods such as SIMS, nano-SIMS, and EA-IRMS.

Ongoing projects: How will cyanobacteria survive dormancy in warmer climate and start blooms in the future? (Carl Tryggers stiftelse 2026-2028, supervisor: Malin Olofsson)
