About me

I am Associate Professor in Pediatric Science at Karolinska Institutet. My research aims to identify the most important familial and sociocultural drivers of obesity early in life, to investigate how lifestyle patterns develop across generations, and to develop effective treatment programs. Other interests include psychosocial development in childhood and psychometrics, especially development and validation of questionnaires related to eating behavior and feeding practices. I am also senior lecturer at the Department of Food, Nutrition and Dietetics of Uppsala University where I teach and supervise students on different levels. 

Childhood obesity has been in focus for my doctoral thesis (2009, Lund University) and postdoctoral research (2009-2014, Yale University, University of Oregon and University of Oxford). My national and international assignments include positions as Scientific Secretary for the Swedish Association for the Study of Obesity (SFO) 2013-2015 and membership in the Childhood Obesity Taskforce (COTF) of the European Association for the Study of Obesity (EASO), 2007- 2016 and board of the European Childhood Obesity Group (ECOG), 2014-2017. In 2015 I organized ECOG:s 25th European Obesity Childhood Obesity Congress that took place in Stockholm. Currently, I am member of the Expert Group in Nutrition and Public Health of the National Food Agency (Livsmedelsverket). I am also affiliated with the Unit for Biocultural Variation and Obesity at the University of Oxford and with the Oregon Social Learning Center, Eugene, USA.

Research description

My research group at Karolinska Institutet examines determinants and consequences of obesity in preschool age as well as effectiveness of different treatment approaches. We are also interested in scale development, psychometrics and survey design.

One of the main projects is a randomized controlled trial, the More and Less Study, testing different treatment options for preschoolers with obesity. We have completed the active phase of the intervention, which was the focus of the doctoral thesis of Anna Ek, for whom I was main supervisor, defended in September 2016. Currently, another doctoral fellow, Maria Somaraki, vid Uppsala University, is following all families for four years. I am the main supervisor for Maria together with Anna Ek as co-supervisor who also continues as a postdoctoral fellow in the project. In addition, I also supervise Karolin Bergman, at Uppsala University, who studies the construction and understanding of state dietary advice. In addition, since June 2017 I supervise Pernilla Sandvik, a postdoctoral fellow at Uppsala University who examines the prevalence and determinants of picky eating early in life. 

My research has been funded by Swedish Research Council, Swedish Medical Society, FORTE, VINNOVA, EU HORIZON 2020 and other funding bodies (for complete list see my CV).
