Experience
Hallo! I am very bad a these things, but I am Marthe Olivia Harme Forus (yes, I have four names). I have a bachelors in Mathematics from the Univerisity of Oslo and I am a master's student at the University of Michigan. I've also recently decided to pursue a master's in applied economics for professional reasons. Iam not sure if I want to pursue a PhD in the future; however, hopefully this portfolio will help me expand and discover my research interests.
My primary research interests involves monetary economics and utility theory, however, I am also interested in the following areas
- Behavioral Economics: Social preferences, rationality, environmental behavior.
- Labor Economics: Applied microeconometric methods, labor supply theory.
- Topology: Topological data analysis, geometric machine learning, manifold learning.
- Stochastic Processes: Stochastic differential equations, stochastic geometry, asset pricing.
