Maria Waltmann
PhD candidate
Stephanstraße 1A
04103 Leipzig
Germany
During her undergraduate years at the University of Heidelberg (B.A. Philosophy and English Literature, B.Sc. Psychology), Maria acquired a taste for neurocognitive research in psychiatry. For her undergraduate dissertation, she worked on the effects of SSRIs on emotional processing in a healthy volunteer model of depression at the Psychopharmacology and Emotion Research Lab (PERL) in Oxford. She followed this up with a degree in Neuroscience at King’s College London, where she worked with Dr. Gemma Modinos on functional connectivity of the striatum in schizotypy using multi-echo resting-state data. In November 2017, Maria joined our Lab to investigate the shared and differential neurocognitive mechanisms of obesity and binge eating disorder, employing behavioural and MR imaging techniques informed by computational modelling.
