About me

I earned my PhD in 2015 with a thesis named "Early life origins of asthma - genetic and environmental factors in twin and kin" at the Department of Medical Epidemiology and Biostatistics. My studies focused on potential risk factors during the period around pregnancy and subsequent childhood health.

After finishing my PhD studies I pursuied my clinical career as a medical doctor, and currently work as resident in obstetrics and gynecology at Visby Lasarett, Gotland. 

In parallell with clinical work I have continued doing research and I am now a post-doctoral fellow in Olof Stephansson's research group within Reproductive Epidemiology, at the Division of Clinical Epidemiology. 

Research description

Current research area

My projects focuses on health care determinants on pregnancy outcome, and more specifically safe deliveries for both mother and child. We have recently published a paper on the Association between travel time to delivery unit and unplanned out-of-hospital birth, infant morbidity and mortality. The study can be found here.

During the last year, I am also involved in projects on COVID-19 during pregnancy, within a Scandinavian collaboration named Scandinavian studies of COvid-19 in PrEgnancy (SCOPE).

Description of PhD studies and prior projects:

During the last decades there has been an upsurge of studies investigating how early life events or exposures may affect subsequent health outcomes of the child, such as childhood asthma and lung function. Much focus has been put into the idea of how our future may be programmed already in utero or during our first months in life. By combining data from national health registers such as the National Patient Register, the Prescribed Drug Register and the Medical Birth Register, prospectively collected clinical material and questionnaire data, with twin- and family based designs, the studies included in my thesis aimed to disentangle familial genetic and environmental confounding from causal mechanisms leading to asthma. I have focused on the role of fetal growth and exposure to antibiotics, and the risk of developing asthma/lung function restriction. We have further investigated the potential role of early antibiotic exposure and the risk of developing very early onset inflammatory bowel disease. I have also worked with validation studies of asthma in the Swedish population-based registers.
