Biography


After getting an M.D. degree in 2014, I defended my awarded PhD thesis on the brain changes of morbid obesity and weight loss surgery in 2015 and received Associate professorship (Title of Docent) in Cognitive Neuroscience in 2018. I am currently Principal Investigator of the FinnBrain Neuroimaging Lab and the work is related to solving the mysteries of the developing brain. I was the director of Turku Brain and Mind Center 2023 - 2025. As of May 2026 my research continues in the Auria Biobank, but I maintain close ties to UTU through FinnBrain and I take part as a senior consultant for InterLearn CoE, Right2Belong project, Turku Brain and Mind Center, and many other parties.

Teaching

I am an enthusiastic techer and teaching development is close to my heard. I have taken part in multiple awarded pedagogical development projects relating to learning material development, student feedback, and peer-assisted learning. I have wide mentoring and tutoring expertise from undergraduate students to post doctoral fellows.

I have had seminal role in the launch of Human Neuroscience Master's Programme at the Turku Brain and Mind Center, and I served as the head of the programme 2023-2025.
