Biography

Though I have lived in Turku for about three decades, I never forget to mention that I was actually born in Tampere (1992). Fast forward to present, I'm married with two daughters and a dog, and I work as a postdoctoral researcher in the Luminous Materials and Devices group.

I guess my interest in physics (and especially theoretical physics) has something to do with my passion for problem solving and the awe of discovery; It really is miraculous how much you can make sense of Nature with just pen, paper, and wit (and Mathematica).

When I'm not in Quantum studying decoherence or polaritons - or with my family - you can probably find me from the local taekwondo gym.

Teaching

I have run the exercise classes of Quantum Mechanics 1A in 2020-2023, lectured Quantum Information in 2023, and worked as a BSc supervisor in 2024.

Research

My doctoral dissertation ("Decoherence and reservoir engineering in linear optical systems") was about modeling open-system dynamics and decoherence with linear optics. Decoherence is commonly seen as bad, as it destroys the delicate quantum properties important for many applications, but here I found ways to use it for good. For example, I showed how to improve precision in parameter estimation with decoherence.

Currently, I'm working as a postdoctoral researcher in the LMD group. I try to find out if the concepts of open quantum systems can help in understanding OLEDs, their electrical excitation, and triplet harvesting with polaritons.
