About me

I am an early career researcher in genetic epidemiology with a focus on psychiatry. I investigate genetic and psychological risk factors for psychiatric problems (primarily depression, anxiety, stress-related disorders) and the contribution of psychiatric risk factors to somatic health and disease across the lifespan. My research joins genetic, epigenetic and life course approaches using population-based samples with available genetic data (e.g. Swedish Twin Register, UK Biobank).  

Research description

My current projects are focused on:

  • Determining why some individuals develop mental and somatic health problems after serious psychological trauma, but others are resilient. I am joining genomics methods (e.g. polygenic risk scores and genetic correlations) with objective indicators of psychological trauma (e.g. childhood adoption, bereavement) to investigate this question.
  • Investigating genetic relationships between psychiatric disorders and somatic health (e.g. asthma, cumulative health decline in older populations) to understand better the underlying shared genetic risk factors behind the high co-morbidity of various mental and somatic health problems.
