Min hovedforskningsinteresse er i numeriske metoder for difflikninger. Jeg er spesielt interessert i metoder som bevarer underliggende geometriske egenskaper (f.eks. symplektiske metoder og volumbevarende metoder).
Jeg er også interessert i tverrfaglig bruk av matematikk og numerikk, spesielt rettet mot medisinske anvendelser, f.eks. bildeanalyse og modellering av fysiologiske prosesser eller maskinlæring for bildeanalyse og diagnostikk.
