About me

  • I have been involved in suicide-related research since 2011, at the National Centre for Suicide Research and Prevention (NASP), Solna campus. Since then, I have led projects at NASP/CHIS which are related to our aims to examine and report epidemiological findings and patterns in suicide rates, suicide prevention-related evidence-based recommendations, and expedite public health-related reports and communications. I am affiliated to the department of LIME, KI (Learning, Informatics, Management and Ethics, ̽»¨¾«Ñ¡), and to CHIS, SLSO (Centre for Informatics, Health economics, and Health Services Research, Region Stockholm). I have a background in experimental psychology (BSc., MSc., Psych.). But like my suicide research, my doctoral project about Screen Time focuses on ̽»¨¾«Ñ¡ aspects relevant to public health sciences.


    My doctoral project can be summarized as 'Screen Time Effects on Adolescent Mental health' (STEAM) (SV. 'Skärmtidseffekter pÃ¥ unga personers psykiska hälsa'). I primarily look at how adolescents' screen time increases their longitudinal progression of depressive symptom, and to some extent suicidal thoughts and anxiety. I focus on two aspects which seem to buffer such screen time effects, namely Coping behaviors and Sleep habits. Within the STEAM project, I utilize research data collected within two previous cluster randomized trials: the YAM 

  • and SUPREME trial.

    My office is located at Granits väg 4, Solna (entrence floor).

Teaching

  • I occationally teach statistics at the department of psychology, Stockholm University, with my co-supervisor Joakim Westerlund. Together with my main supervisor, Gergö Hadlaczky, and my co-supervisors, I sporadically co-supervise students writing their BSc. or MSc. theses within the field of public health-related psychological medicine. I sometimes give guest lectures to other universities or public units. I sometimes organize journal clubs at NASP.
