Malin Olofsson
Marine biologist focusing on phytoplankton-bacteria interactions and nutrient fluxes. My research questions adress phytoplankton-bacteria interactions and nutrient fluxes using secondary ion mass spectroscopy (SIMS), transcriptomics, and metabolomics. I have studied a diverse range of phytoplankton from filamentous nitrogen fixing cyanobacteria to diatoms and dinoflagellates.

Presentation

I recieved my PhD in Marine Sciences at the University of Gothenburg in June 2018. During 2018-2019 I worked as a researcher at SMHI. From July 2019 until 2021 I will spend my first two years of my Post Doc in Athens, GA, in the US. I will be back in Sweden for my third year suing the summer 2021. My project is about phytoplankton derived metabolites trasnferred to bacteria during various environmnetal conditions.
