Om mig
Jag är adjungerad professor och forskargruppsledare inom neuroradiologi med fokus på neurodegenerativa och neuroinflammatoriska sjukdomar.
Efter att ha tagit läkarexamen vid Karolinska Institutet (KI) 2012 gjorde jag min Allmäntjänstgöring vid Västmanlands sjukhus Västerås och min Specialisttjänstgöring i Radiologi vid Karolinska Universitetssjukhuset 2014-2019. Därefter fullföljde jag en subspecialisering i neuroradiologi 2019-2022.
Akademiskt började min bana 2009 då jag gjorde mitt vetenskapliga projektarbete för läkarprogrammet inom detektion av mikrohjärnblödningar vid Alzheimers sjukdom. Min doktorsavhandling, som blev klar 2015, fokuserade på Neuroradiologiska aspekter av Multipel Skleros (MS). Sedan genomförde jag min postdoc vid Massachusetts General Hospital och Harvard Medical School. Där fokuserade mitt arbete på MS-diagnostik och ett kombinerat användande av 7 Tesla MR, PET-MR med 11C-PBR28 (andra generationens TSPO-markör för mikroglia) och Human Connectom Scanner med 300 mT/m gradienter (jämfört med 40-80 mT/m på vanliga magnetkameror). Jag fortsatte i Boston även mitt arbete med att utveckla och validera tekniker för myelinkvantifiering.
Vid min återkomst till Karolinska etablerade jag vår forskargrupp vid Institutionen för Klinisk Neurovetenskap på KI, där vi fokuserar främst på kvantitativa bildtekniker och deras applikation för att förbättra diagnostiken och bedömning av terapisvar vid exempelvis MS, demenssjukdomar, rörelsestörningar och ALS.

- Swedish Research Council1 januari 2024 - 31 december 2027Background: Amyotrophic lateral sclerosis (ALS) is a fatal disorder with heterogeneous clinical expression. While overt morphological findings are often preceded by hypometabolism in ALS, FDG-PET is sparsely used in routine clinical practice due to costs and a somewhat uncertain diagnostic/predictive value. Meanwhile, GlucoCEST MRI is a novel radiation-free method for imaging metabolism that has yet to be applied in ALS.Aim: To evaluate the feasibility and accuracy of GlucoCEST MRI for assessing brain metabolism in ALS and study its diagnostic and predictive value.Methods: A prospective study with 120 persons with ALS and 60 matched controls will be conducted at Karolinska University Hospital using a second-generation clinical 7 Tesla MRI scanner. GlucoCEST will be processed and analyzed using advanced post-processing techniques and compared to the gold-standard, FDG-PET imaging, in patients. Patients will be longitudinally followed comprehensively over up to 4 years.Significance: GlucoCEST can integrate metabolic and structural information from a single scan to detect early neurodegeneration at a lower cost and with less patient risk and -burden than FDG-PET. As a radiation-free technique, the method is especially suitable for precision medicine approaches since it can track disease progression over time to advance our understanding of neurodegenerative disease processes and monitor the efficacy of emerging disease-modifying treatments in clinical trials.
- Swedish Research Council1 december 2023 - 30 november 2027This translational project explores mechanisms and pathophysiology, prevention and outcomes related to long-term neurocognitive decline and risk for dementia after major surgery. The ultimate goal is to provide novel prognostic and therapeutic strategies and patient-centered guidelines for safer perioperative care. We hypothesize that adverse immune response signatures to surgical trauma with impaired periphery-to-brain communication leads to unresolved systemic and neuroinflammation with risk for neurocognitive decline and dementia. Using comprehensive clinical and experimental platforms in man, animals and cells, we will in standardized surgical cohorts in Part A define a longitudinal in-depth immunological, transcriptional, and soluble atlas with a periphery-to-brain axis coupled to hard adverse brain outcomes related to neuroinflammation, neurodegeneration and risk for dementia. Key findings from this effort will in Part B be mechanistically explored in established animal models and in vitro systems to provide in-depth knowledge on targets for prognostic and possibly therapeutic strategies. Information from preclinical and clinical investigations (Part A-B) on precision-based immune signatures will be prospectively validated in broader surgical populations to search at-risk patients (part C). This knowledge will ultimately serve as base for novel perioperative guidelines and therapeutic strategies to prevent neurocognitive decline or dementia after surgery.
