About me

I was born and raised in Germany and received my degree in midwifery from the Rheinische Friedrich Wilhelms University of Bonn, Germany in 1996. Since 1999 I live in Stockholm, Sweden, where I furthered my practical and theoretical skills as a midwife. I am currently a lecturer at the Midwifery programme at the Department of Women’s and Children’s Health at KI, where I am teaching and supervising master students.

I am also a member of the organizing committe of the "Neurobiology of Parenting" conference, to be held in Stockholm, Sweden (August 19-21, 2015). Please see the link above.

Languages: Swedish, English, German.


1996 Registered Midwife, Rheinische Friedrich Wilhelms Universität, University Hospital, Bonn, Germany


Doctoral degree

2009–09-21 Thesis: “Mother and newborn adaptations after birth: Influence of administration of oxytocin and epidural analgesia during labour”, Karolinska Institutet

Research description

For my thesis, I have studied the effects on mothering and breastfeeding of different labor ward routines, including pain relief by epidural analgesia and augmentation of labor through intrapartum oxytocin administration. For my post-doctoral studies at the Department of Psychology, University of Toronto (2012/2013), I worked with Professor Alison Fleming and Dr. Meir Steiner on a large, Canadian longitudinal, prospective and multi-center cohort study entitled “Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN)”, a project designed to understand the pre- and postnatal (up to 10 years) influences on maternal health and child social-emotional and cognitive development, focusing on genetic and environmental influences.

As a recently appointed fellow of the Fraser Mustard Institute for Human Development at the University of Toronto, I am also working with another Toronto Birth (and family) Cohort (the OBS). The focus my work on both these cohorts has been to better understand factors that regulate birthing and breastfeeding by the mothers and the effects of these maternal outcomes on child development.  Dr. Jonas has received funding from various funding agencies including the Swedish Council for Work Life and Social Research (FORTE), the Fernström Foundation at KI and Sällskapet Barnavård at Karolinska Hospital, and by a Canadian Institutes for Health Research grant (Fleming, P.I.).
