FinnBrain Birth Cohort study

InterLearn Center of Excellence

Neuroscience, Brain development, Obesity, Pleasure in the brain, Eating, Exercise, Social touch, Neuroimaging, Magnetic resonance imaging (MRI, fMRI, dMRI), Positron emission tomography (PET). Connectomics, Whole brain modelling. Emerging expertise in population neuroscience.

We study how early life exposures, genes and environment shape the brain structure, brain function and how these relate to health and wellbeing.

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.

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.
