Short presentation

Doctoral Researcher in Stochastic Control Theory in professor Erik Ekström's group.

My first published article considers a two-player signaling game with stopping times. The second and third submitted articles study an irreversible investment problem with the novelty for the decision-maker to control their learning process. My current work (together with prof. Erik Ekström and Henri Doerks) is a statistical fastest detection problem with three independent Brownian motions.

Keywords

• stochastic control
• optimal stopping
• game theory

Biography

Background

Before starting my PhD studies in Uppsala, I completed Master of Science degree in Applied mathematics (2017) and Master of Social Sciences degree in Economics (2020), both in University of Helsinki. In the mathematics degree my thesis was about BSDEs and their general theory, whereas my economics thesis revolved around a certain continuous-time principal-agent game. My current research (luckily enough!) combines these two areas of research.

Other activity

In addition to my doctoral studies, I'm currently and previously involved in certain elected doctoral student organisation and doctoral student representation activities, namely:

2024-2025: Re-elected as the chairperson for SFS Doctoral Committee

2023-2024: Chairperson for SFS Doctoral Committee (representing ~20000 doctoral students nationwide)

2022-2023: Chairperson for the Doctoral Board of Uppsala University (representing ~2400 doctoral students)
