Maria Poessel
PhD candidate
Stephanstraße 1A
04103 Leipzig
Germany
Maria Poessel studied Psychology at the University of Leipzig, which she finished in 2013 with her thesis about the socio-sexual development of sexual child Molesters and Pedophiles in early childhood.
She joined the O’Brain-Project in spring 2013. Her current research focus lies on olfaction in obesity and the influence of odor stimulation on decision making. For the data collection she utilize behavioural and later functional magnetic resonance imaging or functional MRI (fMRI) paradigms. For the olfactory data acquisition, specifically, she apply Sniffin stics and an olfactometer.
