Leif holds a master's degree in economics from Ludwig-Maximilian University in Munich. He previously worked as a an intern and research assistant at the renowned research institution, the ifo Institute for Economic Research in Munich. Through his studies and work at Vista Analyse, Leif has gained a solid understanding of both theoretical, empirical, and model-based analysis, which serves as the foundation for data-driven and policy-relevant economic analysis.

He has broad thematic experience from project work at Vista Analyse, including power and energy, energy efficiency, the climate and the green transition, nature and the environment, construction, innovation, health economics, and local and regional development. The common denominator in these various projects is the use of economic methods and tools to illuminate the issues. Vista Analyse often employs methodological triangulation, where issues are examined from multiple perspectives using various information sources and tools. This can include the application of economic theory, descriptive statistics and data presentation, regression analysis, model analysis, impact analysis, surveys, interviews, and document analysis. Leif has utilized all these tools in his project work. He also has experience with scenario-based numerical modeling from his master's thesis, where he examined the role of carbon capture and storage in the European power market towards 2050.

Additionally, Leif has experience with evaluations and the Quality Assurance (KS) scheme in the Norwegian state's model for large public investments.
