In 2015 LIGO experiment detected for the first time gravitational waves. These gravitational waves originated from a merger of black holes in which energy equal of three solar masses was released in gravitational waves a billion years ago. This detection, recognised with a Nobel prize, marked the dawn of a new era in cosmology and astrophysics.
My research is closely related to gravitational wave observations. Various cosmological and astrophysical processes produce gravitational waves and in near future many new experiment search for gravitational wave signals. I study what kind of gravitational wave signals different cosmological processes produce and how by observing these signals we can look for answers to open questions in modern cosmology such as: What is dark matter? What explains the baryon asymmetry in the Universe? What happened during the very first seconds in the early Universe?
I’m from Joensuu. I studied physics at University of Jyväskylä, from where I got my degree of doctor of philosophy in 2016. After that I have worked as a post-doctoral researcher in Tallinn in the laboratory of high-energy and computational physics (2016-2018), and at King’s College London in the theoretical particle physics and cosmology group (2018-2020). Currently I work as a post-doctoral researcher in Barcelona at the institute of high-energy physics (IFAE).
