Kort presentation
Huvudfokus för min aktuella forskning är inom radiologi, biomarkörer i cerebrospinalvätska och patofysiologi främst inom sjukdomsgruppen hydrocefalus. Har även pågående forskning inom Parkinsons sjukdom, multipel skleros, neurointensivvård samt neurologiska komplikationer till COVID-19.
