Biography:

2019 -   

Post Doc at the Neurobiology Research Unit

2018 - 2019

Post Doc at the Cervenka Lab, Center for Psychiatry Research, Karolinska Institutet. 

2013 - 2018

PhD student at the PET-group, Center for Psychiatry Research, Karolinska Institutet. The PhD focused on pharmacokinetic and
statistical modelling of neuroimaging data as well as investigation of in vivo neuroinflammation in patients with psychosis and
schizophrenia.

2012 - 2013
