Johanna Stadmark
Researcher

My interests cover scientific questions on silica cycling over different time scales, how the Baltic Sea functions and how to mitigate eutrophication. I also spend my time on understanding how research environments can be organized to support equal opportunities.
The Baltic sea suffers from high nutrient concentrations and large areas of hypoxic water and sediment and several methods to cure this area are suggested. I have worked in projects where we have tried to disentangle the effects of different stressors over time. We especially have focused on the coastal zone and measures that are already implemented. We work actively with dissemination of our results to decision makers and the public.
In the Horizon 2020-funded project Baltic Gender (www.baltic-gender.eu), our aim was to increase the proportion of women in senior positions in marine science technology in countries surrounding the Baltic Sea. The project also aimed at presenting role models in marine science and technology, and show how researchers (women and men) reflect about their careers and familiy situations. I was the WP-leader of the part of the project that focuses on career advancement. Currently I am using my experience from Baltic Gender in the Action Group for equality at the Faculty of Science, Lund University.
