Forskinga mi fokuserer på topologiske metodar i statistikk og maskinlæring. Topologisk dataanalyse handlar om analyse av dataform. Forskinga mi inneber effektiv koding av data til simplisielle kompleks (topologisk representasjon og sparsifikasjon), validasjonsmål for urettleia persistent homologi og effektive vektorrepresentasjonar av persistent homologi. Eg nyttar òg metodane i biomedisin og geofysikk.
