"A machine-learning approach using brain functional and structural connectivity metrics for differentiating patients with schizophrenia from healthy subjects"

My thesis work is aimed at the use of multimodal neuroimaging data (functional and structural MRI) to investigate properties of brain networks, which can be used for classification of patients with neuropsychiatric disorders and healthy subjects, using schizophrenia as a model phenotype. The work encompasses the characterization of functional and structural brain networks using graph theory, and the training of machine learning algorithms to find those set of network properties which lead to robust classification. Through this work, we expect to gain insight about brain pathology by reverse inference. You can follow the project on ResearchGate.
My thesis advisers are Prof. (Dr.) John P. John (from NIMHANS) and Dr. Kaushik K. Majumdar (from the Indian Statistical Institute, Bangalore)
