Forskningsområden

Jag forskar vid gränssnittet mellan grundläggande utveckling av laserbaserade spektroskopiska tekniker och deras tillämpning inom områden som förbränning, energiteknik, medicinsk diagnostik och kemisk avbildning.

I gruppen för Tillämpad Optik utvecklar vi optiska metoder för in situ realtidsmätning av atomer och molekyler i gasformiga, flytande och fasta prover. Även känslighet, selektivitet och bra kvantifieringsförmåga är viktiga aspekter. Tekniker inkluderar laserabsorption, fotofragmentering och fototermisk spektroskopi, där vi använder ljuskällor i ett brett spektralområde, från ultraviolett till mid-infraröd.

Det finns ett ökande intresse för biomassa som förnybar, CO2-neutral energikälla. Snabb in situ-diagnostik behövs för att bättre förstå, optimera och kontrollera processer relaterade till termokemisk omvandling (förbränning och förgasning) av biomassa. Fokus ligger på detektering av huvudämnena, gastemperatur, sot och oorganiska föreningar, såsom kalium.

Andningsgasanalys har potential att revolutionera icke-invasiv medicinsk diagnostik. Fortsatt forskning behövs för att bättre förstå ursprunget av biomarkörmolekylerna och hur man på ett tillförlitligt sätt kvantifierar dem i utandningsluften. Aktuellt utforskar vi gasformiga signalmolekyler, såsom kolmonoxid, och deras roll i luftvägs- och lungsjukdomar.

Kemisk bildbehandling är ett viktigt verktyg inom livsvetenskap. Vi använder ljuskällor med hög briljans, som kvantkaskadlasrar, för att förbättra tidsupplösningen samtidigt som hög spektral- och spatial upplösning behålls. Målet är att öka analyshastigheten och möjliggöra undersökning av snabba biologiska processer och reaktioner.
