I graduated from the Department of Psychology at University of Turku in 2003. In my master's thesis I looked into the processing of emotional content in the parafoveal vision in reading. In my PhD studies I studied reading development using eye movement tracking as a tool. I completed my PhD in 2011. Since then, I've continued examining reading and writing of early readers using eye tracking. I've gained media coverage with my findings that hyphenation at syllable level slows down readers already very early in their education.
