Short presentation

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

My first project (Hiring and Firing: a signalling game) revolves around two-player signaling game in a labour market setting. My second project (Learning by doing under irreversible investment) presents a control problem where learning rate is increased.

My research interests include optimal stopping time problems, hiring-firing problems, principal-agent problems and stochastic differential equations in general.


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 backwards stochastic differential equations 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 many student organisation and quality assurance activities, namely:

2023-2024: Chairperson for SFS Doctoral Committee,
2022-2023: Chairperson for the Doctoral Board of Uppsala University
