About me

  • Professor of Clinical Epidemiology, focusing on Obstetrics-Gynaecology at the Department of Medicine, Solna as from 1 July 2021.


  • Pregnancy and childbirth is associated with adverse outcomes among women with obesity, previous bariatric surgery, smokers and in women with chronic disease such as diabetes, depression, rheumatoid arthritis, endometriosis, polycystic ovary syndrome (PCOS) psychiatric and inflammatory bowel disease. Among women with chronic disease safety in drug treatment is important but also to learn more about disease progression due to pregnancy.

    As a clinical obstetrician I have a strong interest in factors influencing labor progress and risk factors for dystocia. We know that dystocia is associated with increased risks of cesarean section and maternal complications including postpartum hemorrhage but also risk for asphyxia in the newborn. The aim is to find characteristics in mothers and during delivery, which guide us in the clinical setting and consequently may reduce maternal and neonatal morbidity due to dystocia.

    My research group includes midwives, physicians in obstetrics and gynaecology and pediatrics as well as nutritionists, epidemiologists and biostatisticians. My ambition is to perform research focused on the clinical setting. The information mostly used in my studies is based on the Swedish Medical Birth Register (MBR). From 2013-2019 I was head and the chairman of the Swedish Pregnancy Register (www.graviditetsregistret.se).

    Our research is funded by The Swedish Research Council, FORTE, Belmont Forum, NIH, Stockholm County Council, Karolinska Institutet and other funding organisations.
