About me

I am a research group leader for a research group, which right now consists of one PhD student, one postdoc and one senior lab manager. Furthermore, I am Head of the Division of neurogeriatrics, which is composed of 65 employees and 12 research group leaders. In addition, I am as a researcher involved in teaching at both the masters, advanced and doctoral level and is also a course director for a course in Neurodegeneration here at the department of NVS.  I am a research representative in the Committee for Doctoral Education at KI and assignments such as member of the KID-steering group, Teaching and Learning steering group. These roles give me a lot of input and knowledge on how KI is working on many levels and how we all can impact our common future. I also have a big interest in leadership and have been part of KI's supervisor and leadership courses for many years. This has given me important reflections on my own leadership style and also I meet a lot of interesting people at KI and SLL, which is a benefit for my research career.

Research description

In the Karlström lab we focus on CADASIL (cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy), the most common familial form of small vessel disease. The condition leads to a series of increasingly severe strokes and dementia. CADASIL is linked to the Notch3 protein which is an important signaling protein allowing cells to communicate with one another. Mutations in the NOTCH3 gene result in misfolded Notch3 accumulating around small and middle-sized arteries throughout the body. At present how these Notch3 deposits affect the surrounding tissues is unclear. The disease mechanisms may be further complicated due to altered Notch3 signalling. A number of genetic disorders such as familial Alzheimer’s disease are directly linked to protein misfolding, which strongly suggest that abnormal protein accumulation and deposits play a direct cytotoxic rile in the disease. 

We aim to better understand the molecular mechanisms of this condition in order to develop therapeutics to tackle CADASIL. We hypothesise that if we can harness the immune system to clear the Notch3 deposits we can halt or potentially reverse CADASIL progression.

A successful treatment for CADASIL would provide a much-needed cure for many individuals and would pave the way for new small vessel disease therapeutics. Our inter-disciplinary project team has clinical and preclinical expertise in CADASIL, and vaccine development and drug discovery competence.


Another part of my research is related to Alzheimer disease (AD). In my group we look specifically at the cellular and biochemical processes that lead to the disease. There is a common theme for both SVD and AD and also for many other neurodegenerative diseases, that is formation of aggregated peptides. It is a challenge to inhibit the formation of these aggregates, since other important signaling pathways can be disturbed, which could lead to serious side effects. Our aim is to come around this by knowing in more detail how it works and hopefully lead to development of better and safer medicines for treatment of CADASIL and Alzheimer disease.

Teaching portfolio

My subject area is Neurodegenerative disorders, with focus on Alzheimer’s disease and small vessel disease/vascular dementia. I am course leader and lecturer since 2013 for the Frontiers in Neuroscience master block (3rd semeter): “Neurodegenerative disorders I – from molecule to treatment, which is a combined PhD course and on the master program in Biomedicine at KI.  The course in provided 1 week/year.

I teach on the 1st semester on the master program in Biomedicine in the Neuroscience block with the topic ”Vascular dysfunctions and Neurodegenerative disorders”.


2014-2018 Lecturer on the 1st semester Biomedicine program in Pharmacology with toxicology. Lecture: Clinical and basic mechanisms behind Alzheimer disease.

2018 Teaching for clinical Neurologists from China in ”Molecular aspects on Alzheimer disease”

I also teach in the Leadership course for research group leaders and have between 2010 and 2020 been a course leader for this 2 weeks course/year. My subject has been to run workshops called ”Back stage meetings”which is a structured way to perform problem solving in the aspects of leadership.

Lastly, since I have been a course leader for the PhD supervisor course between 2010 and 2019 I have been involved in many lectures within the course (provided 4-6 weeks per year) but also at different internal KI events organised by Junior faculty, KI Postdoc association, KI-NIH program, but also given and helped with design of courses and lectures for external universities such as Helmholtz Association (two times) and Muhimbili Medical and Health University in Tanzania (five times).
