Forskningen syftar till att reda ut mekanismer i samspelet mellan mikrober och värdceller för att bättre förstå orsakerna till infektionssjukdomar, och för att hitta nya möjligheter att förhindra och bota dem. Min forskargrupp har bland annat visat hur små membranblåsor som frisläpps från bakterier påverkar värdceller då de innehåller specifika proteiner och andra makromolekyler som kan ha effekt på värdens immunsystem och även de cellulära signalmekanismer som spelar stor roll bland annat vid tumörbildning och cancersjukdom.

Jag är medlem i forskarkonsortiet Umeå Centre for Microbial Research (UCMR) som utgör den vetenskapliga miljön där The Laboratory for Molecular Infection Medicine Sweden (MIMS) etablerades. Jag har som representant för MIMS deltagit vid internationella rekryteringar som genomförs inom ramen för The Nordic EMBL Partnership for Molecular Medicine när nya gruppledare knutits till de olika noderna i Danmark, Finland, Norge och Sverige. Inom MIMS har jag bedrivit forskningsamarbeten som resulterat i sampubliceringar av vetenskapliga artiklar med flera av de unga gruppledarna Jörgen Johansson, Richard Lundmark, Emmanuelle Charpentier och Andrea Puhar.
