I am a researcher both at the Department of Clinical Neuroscience and the Department of Medical Epidemiology and Biostatistics at Karolinska Institutet.
I completed my M.Sc. in Criminology at Stockholm University and obtained my PhD at Karolinska Institutet. I have completed postdoctoral fellowships at the University of Oxford and at Karolinska Institutet.
My main research areas are pharmacoepidemiology and the psychiatric epidemiology of traumatic brain injury. My research is register-based, meaning that I analyse data from Swedish national registers and the Swedish Twin Registry.
In my pharmacoepidemiological research, I study the risks and benefits of common medications with a specific interest in psychiatric and behavioural outcomes such as depression, anxiety, suicide, overdoses, accidents, violence and other crimes. For this purpose, I use Swedish pharmacy, healthcare, sociodemographic, crime and death registers, and I study nationwide cohorts of individuals who take different medications. I have previously published studies on the psychiatric and behavioural outcomes of e.g. antidepressants, nicotine replacement therapy, antiepileptic drugs, cholesterol-lowering medications, heart medications, and medications for treating substance use disorders.
In my traumatic brain injury research, I examine the link to psychiatric disorders, violence, substance misuse, suicidal behaviour and functional impairment. I also study the effectiveness and safety of pharmacological interventions in patients with traumatic brain injury, with a specific focus on psychotropic and pain medications. I use Swedish pharmacy, healthcare, sociodemographic, sick-leave, crime and death registers to follow up patients who have been treated for varying severities of traumatic brain injury.
I am also involved in epidemiological research projects on substance use disorders, behavioural addictions, crime, domestic violence, suicidal behaviour, and risk assessment tools.
My research is funded by ALF Medicin, Karolinska Institutet Funds and Systembolagets Alkoholforskningsråd.
