CEDI - Centre for Eating Disorders Innovation

Denna sida på svenska

The Karolinska Institutet Centre for Eating Disorders Innovation is funded by the Swedish Research Council. Our goal is to push the boundaries of research in the area of eating disorders by engaging scientists from a variety of disciplines to rapidly accelerate our understanding of the causes of and treatments for eating disorders.

CEDI team at KI

At the Centre for Eating Disorders Innovation (CEDI) we are dedicated to applying novel and emerging methodologies and technologies to elucidate causal mechanisms underlying eating disorders. Our ultimate goal is to rigorously apply findings from genetic, biological, and environmental risk investigations to refine and personalize detection, prevention, and treatment of eating disorders.

At CEDI, we are dedicated to mentorship of trainees at all levels to cultivate the next generation of eating disorders scientists. From neuroscience to clinical research, our faculty and global collaborators are dedicated to our education mission. In addition, we are passionate about dissemination of science. Through public lectures, invited lectures, publications, media, and social media, we will translate often complex scientific results into readily understandable concepts for the public.

Our singular goal is to rapidly advance our understanding of eating disorders. By engaging scientists from a variety of disciplines and examining eating disorders through new lenses, we aim to build a comprehensive understanding of the role that both genetics and environment play in eating disorders risk and maintenance.

Recent symposium

On Oct 2, 2017, we hosted a half-day symposium together with the Stockholm Center for Eating Disorders. The conference was held in Aula Medica at Karolinska Institutet between 1 and 5 pm. Most of the lectures were held in Swedish (Yvonne von Hausswolff-Juhlin, Göran Kenttä and Marit Sahlström) while one lecture was in English (Cynthia Bulik). Read more about the event in the Swedish calendar. The lectures were filmed for Swedish television.


Professor Cynthia Bulik is responsible for the centre and you can contact her by e-mail if you have any questions. Operations manager Bengt Fundin and project coordinator Jessica Pege is also available to answer any questions you may have.

Ongoing projects

ANGI - Anorexia Nervosa Genetics Initiative

The Anorexia Nervosa Genetics Initiative (ANGI) is the largest genetic study of anorexia nervosa ever conducted. With colleagues in the United States, Denmark, Australia plus New Zealand, we have collected DNA from over 15,000 individuals with anorexia nervosa and matched individuals who have never had an eating disorder. We have analyzed the whole genomes to identify genes and that affect the risk of anorexia nervosa and help us to understand the biology and improve treatment. Cynthia Bulik is the lead principal investigator and the KI ANGI team leader is Mikael Landén.

BEGIN - Binge Eating Genetics INitiative


BEGIN will be the first and largest genetic investigation of bulimia nervosa and binge-eating disorder. Taking place in the US and Sweden, we will collect DNA and stool samples from individuals with both of these conditions and healthy control individuals in order to identify genes and microbiological factors that contribute to these disorders. We will be the first large study to try to understand how the human genome and the bacteria in our guts interact to lead to and maintain bulimia and binge-eating disorder. Professor Cynthia Bulik is responsible for the project and the BEGIN team includes project manager Virpi Leppä, PhD student Camilla Wiklund, research assistants Malin Rådström and Jessica Pege, Director of ANGI Laura Thornton, database administrators Johan Källberg and Michael Broms, and collaborators from the Centre of Translational Microbiome Research (CTMR) Lars Engstrand and Ina Schuppe Koistinen.

CREAT - Comprehensive Risk Evaluation for Anorexia nervosa in Twins


CREAT is a study of identical twins who are discordant for anorexia nervosa. This means that one twin has anorexia and the other does not. The beauty of this study is that identical twins share all of their genes, so discovering differences between them helps us focus on where to look for causes for this debilitating illness. We will be inviting twins to spend two days with us at Karolinska Institutet and Karolinska universitetssjukhuset for a comprehensive evaluation including neuroimaging, genetics, psychology, and biomarkers. This unique study will help us understand both the biology and the psychology of anorexia nervosa. Jessica Pege is the coordinator for CREAT and the team includes Bengt Fundin, Ata Ghaderi, Elisabeth Welch, Camilla Wiklund, Johan Källberg, Lauren Breithaupt, Chris Hübel, Maria Seidel, Cynthia Bulik, Ricard Nergårdh, and colleagues from Germany (Stephan Ehrlich) and Los Angeles (Jamie Feusner).


IMA is a new study where we use a unique design to explore the relationship between the host genome and its impact on the microbiome over time in individuals with sustained nutritional deficiencies (severe and enduring anorexia nervosa) as well as the effects of refeeding. The study is a collaboration with Stockholm Center for Eating Disorders (SCÄ). Cynthia Bulik is responsible for the project and the IMA team includes project manager Bengt Fundin, PhD student Camilla Wiklund, research nurse Christina Holmén, database administrator Johan Källberg and the FoU-manager at SCÄ Elisabeth Welch.

Binge-Eating Disorder in the Swedish National Registers

Binge-eating disorder (BED) is an eating disorder marked by binge eating (eating an unusually large amount of food and feeling out of control) in the absence of any inappropriate compensatory behaviors. Although BED is a fairly new diagnosis, it has been around for a long time and is the most common eating disorder. We are conducting a series of studies in collaboration with the Swedish National Quality Registers for eating disorders Riksät and Stepwise and colleagues at the Stockholm Centre for Eating Disorders (SCÄ) to understand the nature of BED, how often it co-occurs with other psychiatric disorders like depression and anxiety, how often it includes medical complications, and how individuals with BED utilize medications and healthcare in general. The research team includes Henrik Larsson, Andreas Birgegård, Claes Norring, Yvonne von Hausswolff-Juhlin, Elisabeth Welch, Laura Thornton, Andreas Jangmo, and Hunna Watson, and Cynthia Bulik.

Eating Disorders in the Swedish Twin and Population Registers

Utilizing the rich epidemiological data available in Sweden, trainees and faculty at CEDI are studying a number of important research questions related to eating disorders across the lifespan. Researchers include Shuyang Yao, Camilla Wiklund, Chris Hübel, Anna Hedman, Mattias Strand, Laura Thornton, Henrik Larsson, Paul Lichtenstein, Nancy Pedersen, Ralf Kuja-Halkola, and Cynthia Bulik.
