Neuroscience
how can mathematics, statistics, and machine learning help us understand how the brain works?
Background
The most interesting question in neuroscience concerns the understanding of how the brain works. A large part of the research in this area benefits from neuroimaging, which facilitates the extraction of information from neural activities.
Goals
The goal of this research program is to use mathematical and machine learning methods to uncover neural patterns common across individuals when they perform different tasks and to detect anomalies in brains of individuals with psychiatric disorders.
Broader Impacts
The methodology developed in this line of research promises to empower clinical researchers with modern quantitative tools that facilitate a data-driven diagnosis of brain diseases.
