Sedan 2022 är jag anställd som universitetslektor vid Umeå Universitet. Tillsammans med kollegor vid Umeå Universitet bedriver jag forskning inom projektet Deep Brain Stimulation (DBS) för tvångssyndrom, depression och generaliserat ångestsyndrom. Jag har även pågående forskningsprojekt inom psykiatrisk registerforskning och genetik vid autism i samarbete med Karolinska Institutet. Jag har tidigare disputerat inom området psykiatrisk epidemiologi.
