Jag bedriver forskning på MT-FoU (CMTS, NUS) inom Umeå Hydrocephalus Research Group. Främst arbetar jag med modellering och analys av trycket i hjärnan (intrakraniellt tryck) och flödesdynamik i vätskesystemet som omger hjärna och ryggmärg (cerebrospinalvätskesystemet). Min forskning handlar bland annat om att utveckla och validera protokoll och analysmetoder för lumbala infusionsmätningar, som utförs på Neurologiska avdelningen på NUS. Just nu är jag projektledare för en Nordisk multicenterstudie där vi undersöker om denna typ av undersökning kan användas för att individanpassa behandlingen av så kallad Normaltryckshydrocefalus.

Jag är också aktiv inom MedTech4Health, ett nationellt strategiskt innovationsprogram, finansierat av VINNOVA, där MT-FoU i egenskap av aktör inom Centrum för Medicinsk Teknik och Fysik (CMTF) representerar en programmets regionala noder.

Jag har i grunden en civilingenjörsexamien i Teknisk Fysik från KTH (2008) och disputerade i Medicinsk teknik vid Inst. för Strålningsvetenskaper, UMU i december 2013.
