Research Interests

My research interests are focused on using machine learning algorithms to derive localized cellular and genetic information from structural magnetic resonance images in patients with brain cancer in order to provide clinicians with an imaging-derived biopsy approximation in vivo. By extracting quantitative radiomic features from the images and examining higher-order relationships between these features and histological features of coregistered post-mortem tissue samples, I hope to shed light on the information structural imaging is able to provide that is not visible to the naked eye.
