Industriell bioekonomi och tillämpad beräkningsvetenskap

Jag jobbar med strategiutveckling, och jag vill se en välfungerande svensk cirkulär bioekonomi under min livstid. Jag står bakom en industriell väg till en svensk cirkulär bioekonomi. Ny gränsöverskridande samverkan ska öka förädlingsvärdet i den svenska biobaserade sektorn och konkurrenskraften hos svenska regioner och företag.

Jag jobbar med tillämpad beräkningsvetenskap. Jag gillar de utmaningar som kommer med att lösa verkliga problem snabbt och noggrant med billiga datorer. Jag gör det genom att inkludera modern beräkningsvetenskap i lösningsmetoderna, kombinerat med djup kunskap om det underliggande fysiska problemet. Jag gör simuleringar och modellering, och jag gillar problem som är både akademiskt utmanande och industriellt relevanta. Jag har ägnat mycket tid åt att studera strålningstransportproblemet (”Radiative Transfer”), och jag har utvecklat avancerade simuleringsverktyg för ljusspridning i papper och tryck.
