Academic interests

Genetic and environmental influences on mental disorders (depression, eating disorders)
Social and environmental determinants of mental health

Research

I am a PhD Candidate at the PROMENTA Research Center at the University of Oslo. I am currently a Visiting PhD Fellow at the Institute of Environmental Medicine at Karolinska Institutet (supervised by professor Fang Fang).

My PhD project focuses on genetic and environmental influences on wellbeing and risk of mental disorders, in particular on identifying social and societal factors which influence mental health. The project is based on data from The Norwegian Twin Registry, the Norwegian Mother, Father and Child Cohort Study (MoBa), and large-scale population-based data from Statistics Norway.

Alongside my doctoral research, I am involved in research on the genetic and environmental influences on eating disorders. I also have an interest in applied statistics, statistical modeling in observational research, and applying network analysis to advance knowledge on the social correlates of mental disorders. I am also interested in meta-science and have worked on three large-scale replication studies.

My scientific publications are available on my Google Scholar profile.

Objectives: To investigate the perceived risk of psychotropic and mental illness exposures (1) during pregnancy or (2) while breastfeeding on offspring neurodevelopment, and factors associated with this perception in women with past/current mental illness. Design: Cross-sectional, web-based study. Setting: Nationwide in Norway, June 2020-June 2021. Participants: Women aged 18-55 years who were pregnant, recent mothers or planning a pregnancy, and had been offered antidepressants in the last 5 years. Primary and secondary outcome measures: Perceived risk of prenatal and breastmilk exposure to psychotropic medications and maternal mental illness on offspring neurodevelopmental outcomes. Results: We included 448 women: 234 pregnant, 146 mothers and 68 planning a pregnancy. On a 0-10 scale, women perceived antidepressants as least harmful both (1) in pregnancy (mean score 4.2, 95% CI 3.6 to 4.8) and (2) while breastfeeding (mean score 3.8, 95% CI 3.3 to 4.4), relative to antipsychotics, anxiety/sleeping medication or antiepileptics (mean score range: 6.3-6.5 during pregnancy, 5.5-6.2 while breastfeeding). Many participants were unfamiliar with psychotropics other than antidepressants. The perceived risk of mental illness exposure exceeded that of antidepressants (mean score range 5.6-5.9) in both exposure periods. Using general linear models, factors associated with greater antidepressant risk perception in both exposure periods included having lower education, non-Norwegian native language, and employment status (range mean score difference (β): 2.07-6.07). For pregnant women and mothers, there was an inverse association between perceived risk and the perceived antidepressant effectiveness in both exposure periods (range of β: -0.18 to -0.25). Conclusions: In women with past/current mental illness, the perceived risk of antidepressant exposure on child neurodevelopment was lower than that for maternal mental illness. Other psychotropic medications were perceived as more harmful. As medication risk perception influences the decision-making regarding treatment of mental illness, pre- and pregnancy counselling should target women with characteristics associated with higher perceived risk.
