  Södertörns högskola

  Jan 2003 - Jan 2009

  PhD Candidate

  Was working on my Ph.D project on neuroendocrinology, behaviour and endocrine disruption in the fish, the Guppy (Poecilia reticulata), involving behaviour studies, molecular biology, functional brain anatomy, chemical analyses of physiological changes due to altered endocrine functions in the brain.The work also included teaching undergraduate students in laboratory environment and during lectures.

  Sept 2009 - Aug 2013

  Manager of a pilot project in environmental toxicology aiming at examining possible effects of endocrine disruption on developmental gene patterning of the zebrafish nervous system.Continued involvment in the same project as during my Post Doc period with the additional role of discovering new ideas for future projects and acting as co-supervisor of two PhD students planned for dissertating during 2016. Involved in a research project in environmental toxicology which studied physiological and behavioural effects of endocrine disrupting chemicals on exposed fish. The project involved many different aspects of laboratory work and experiments such as development of new molecular biological biomarkers, histological investigation of changes in gonad structure, behaviour studies and work on enzymatic reactions.

  Research Scientist

  My role as a researcher in Environmental Toxicology has mainly been to plan, execute and develop new research projects on the topic of developmental neurotoxicology. I have also worked as a lecturer and main responsible for an introductory course in environmental toxicology. My main research interest since joining the team in Uppsala has been to study functional disturbances of CNS development, caused by environmental pollutants like PFOS, PBDE 99, carbaryl and chlorpyrifos. The experiments have included behaviour studies and analyses of changes in transcription of genes involved in neurotransmitter systems, but I have also developed a curiosity to look further at functional changes caused by these pollutants by planning to involve electorphysiological methods and metabolomics in future studies.

  Goodpoint AB

  Feb 2016 - Jun 2018

  Konsult Kemi och Miljö

  Som konsult på Goodpoint hjälpte jag företag och organisationer i frågor inom kemi och miljö. Mina expertområden, hälso- och miljöpåverkan av miljögifter och läkemedel är baserade på min fleråriga arbetslivserfarenhet inom forskning och utbildning inom ekotoxikologi på universitetsnivå på Uppsala Universitet och Södertörns Högskola. Utöver mina expertområden så arbetade jag bland annat mot byggbranschen som revisor åt BASTA och granskare åt Byggvarubedömningen samt hjälpte företag inom området med att upprätta korrekt miljödokumentation av byggvaror och kemiska produkter.
