My PhD research has centered around social interaction, particularly paradigms and practices related to social touching behaviour.
There's a lot that we don't know about how humans use social touch. What do different types of touch mean? How does the meaning change depending on things like who (e.g. mother, stranger, friend) is doing the touching? Or where (e.g. home, office, hospital) the touching occurs? In my PhD I have been studying these questions using many different methods, such as asking people and imaging their brains. My thesis "Maintaining social bonds via touching: A cross-cultural study " is now available online. I also wrote a brief introduction to social touching to give background to anyone interested (only available in Finnish at the moment).
My other research interests include pain and its relationship to experiencing emotions in the body and combining large scale (e.g. online) data collection with more traditional laboratory-based measurements.
Below you can find some of my publications and teaching materials related to social touch, and if you have ideas or questions you can also contact me directly. Or maybe you'd like to participate in an online experiment or two?
