The medical faculty awards Kathrin Giehl an IPaK travel grant in the context of the ipid4all-application (DAAD) of the Albertus Magnus Graduate Center. She will attend the International Congress of Parkinson’s Disease and Movement Disorders held in October 2018 in Hong Kong in order to present her work on working memory training in Parkinson’s disease using fMRI.
Omer Reiner, cand. med.
Omer Reiner’s primary research focus is the role of dopaminergic pathways in reinforcement learning. He is investigating the effect of nourishment as a primary reinforcer and it’s significance in neural mechanisms underlying behavioral patterns that lead to obesity.

Hendrik Theis, M.D.
Hendrik Theis is a resident physician at the Department of Neurology at the University Hospital of Cologne and a researcher in the Multimodal Imaging Group. His research focus is the dopaminergic modulation of brain networks. He is investigating changes of fronto-striatal connectivity in Parkinson’s patients with impulse-control disorders and he is also interested in reward learning in obesity.

Merle Hönig, PhD
Merle Hönig’s research interest is focused on the investigation of resilience mechanisms in neurodegenerative diseases. As part of her work, she elucidates the role of lifetime factors such as education, occupation, nutrition and physical activity in regard to the occurrence and extent of neuropathology and changes in network function in Alzheimer’s and Parkinson’s disease. In addition, she is interested in genetic and epigenetic changes and how these factors are, in turn, associated with resilience mechanisms.

Kathrin Giehl, PhD
Kathrin Giehl’s primary research focus is to advance the understanding of underlying neural mechanisms involved in Parkinson’s disease. She is particularly interested in elucidating mechanism responsible for distinct cognitive impairments, which are frequently observed in this patient cohort, and to investigate the effects of cognitive training on a neural and behavioral level in order to ameliorate these difficulties. For her research, she utilizes behavioral paradigms and various neuroimaging methods, such as functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET). In addition, she organizes and coordinates a broad range of investigator-initiated and industry-sponsored trials with a focus on neuroimaging and neurodegenerative disorders, especially Alzheimer’s and Parkinson’s disease.
