Undervisning
Jag brukar undervisa i kurser inom Numeriska metoder, Linjär algebra och Analys.
Forskning
Jag forskar inom numerisk analys och beräkningsvetenskap. Framför allt är jag intresserad av att utveckla finita differensmetoder som används för att lösa tidsberoende partiella differentialekvationer.
Du kan hitta mina publikationer i DIVA eller på ResearchGate.
