I completed my Ph.D. in psychology at Karolinska Institutet (2013) where I currently work as a postdoc.
My overall research aim is to better understand the processes that govern emotional learning and regulation in social contexts. More specifically, I focus on the processes underlying fear and safety learning accomplished through own direct experience and through social means such as instruction, observation and interaction with others. I address these issues using different methods including behavioral, psychophysiological and functional magnetic resonance imaging (fMRI).
