Bio

Dr. Yu’s research expertise is in the areas of multimodal neuroimaging (MRI and EEG/MEG) and brain network (or connectome) analyses in dementia and mood disorders. Dr. Yu’s current research focuses on the identification of genetic architecture of brain structural and functional networks in Alzheimer’s Disease (AD) and multilayer brain structure-function connectome changes AD. Specifically, Dr. Yu is interested in identifying associations between the human connectome (measured by functional and diffusion MRI), amyloid-β and tau pathologies (measured by PET imaging data), blood-based microarray RNA gene expression profiles (transcriptome), DNA variations (genome), neurotransmitter receptor density maps (derived from PET), and cognitive decline, as well as neuropsychiatric syndromes in AD. 

From 2017 to 2019, Dr. Yu worked as a Postdoc Fellow in Computational Neuroscience/Psychiatry for the Department of Psychiatry at the University of Pennsylvania. There he conducted studies in functional and structural network analysis in patients with depression and anxiety symptoms. In 2017,  Dr. Yu obtained his PhD in Computational Neuroscience from the Department of Neurophysiology & Alzheimer Center, VU University Medical Center, Amsterdam, The Netherlands. During his doctoral studies, his research included: EEG/MEG network analysis in Alzheimer’s Disease and frontotemporal dementia, developing novel connectivity and network metrics and neural network modeling in neurological disorders. Dr. Yu earned his Master’s (2013) and Bachelor’s (2010) degrees in Theoretical Physics from China.
