Part of his work covers software and system design for scalable, scientific computing. Ensuring scientifically reproducible computation for large scale simulation models is quite complex. Tracking all data sources, their provenance, their transformations to fit required input formats, the tracking of the tools and algorithms used to transform the data, as well as the simulation models that were used, give rise to many challenges. This work addresses this problem as well as efficient ways to add and combine simulation models for innovative and rapid modeling and analysis with integrated validation and data quality assessments.
Mortveit enjoys scientific visualization of spatial phenomena, in particular illustrations of dynamics of large, interaction-based systems involving synthetic information.
