Research at Karolinska Institutet
Karolinska Institutet accounts for the single largest share of all academic medical research conducted in Sweden. The research spans the entire biomedical field – from basic experimental research to clinical studies in collaboration with the health care system. Pioneering research is conducted here in, for example, cancer, neuroscience, immunology, epidemiology, nursing and global health.
Resources in brief

Petter Brodin wants to understand your immune system
Is your immune system functioning as it should? The question is not as simple to answer as one might think. Professor Petter Brodin is trying to understand more about it. At the same time, he hopes to help patients that are severely affected with post-COVID and other conditions where the regulation of the immune system is not working.
Inger Kull: “Young people with allergies are missed in healthcare”
When Inger Kull was a new nurse in the early 1980s, researchers were looking for risk factors. Today she is a professor and prefers to talk about health factors. Thirty years of research on the Bamse-children have provided answers to many questions, but not the most difficult: Why do children develop allergies?
AI researcher Max Gordon: "AI can do the boring things"
The 2023 AI Swede of the Year feels no need to be at the center of research. Yet that is exactly where he is. The orthopaedic surgeon and researcher Max Gordon was an early adopter of artificial intelligence. Now everyone else wants to know how to do it.
Here are our new professors
The immune system of the airways, AI in healthcare, and the prevention of common diseases and accidents are some of the research areas that the new professors at KI are interested in. Every October, it is time for the Professors’ installation ceremony in Aula Medica. Read about our new professors and learn about their research.

A clearer picture of ADHD: focus on function
Over the past 15 years, the number of ADHD diagnoses has risen sharply in Sweden. Is this development reasonable? And what might be the cause? Whilst asking these questions, researchers would also like us to focus less on the diagnosis and more on the functional capacity of people with ADHD.
How old are you – really?
You might be 50 years old, but your body could be as fresh as a 40-year-old’s ‒ or vice versa. Biological ageing has its own pace and rhythm. How we live our lives, what we experience, and the quality of medical treatment we receive all influence how quickly we wear out.
Challenge the sway - Curious about balance
To maintain balance, several factors must align. The inner ears and eyes need to send accurate signals to the brain. Good motor skills and sense of touch, especially in the feet, along with a healthy brain, are necessary. It is not surprising that balance disorders can occur, but how should they be treated?
How screen habits affects children's health
Screen time is often associated with poor health in young people, but it is more complicated than that, say researchers. We are affected, but differently and not just negatively. What we do on our phones – and what we do when we are not using them – also plays a role in our well-being.
Cleaning – not to be swept under the rug
In the healthcare setting, keeping things clean can be vital to prevent the spread of dangerous bacteria. But in a household, what’s best for your health – to live pretty dirty or to be a clean freak? Read our interviews with the researchers who have a pure interest in cleaning.
