Research Interests
Our brain cancer research has been focused on characterizing brain tumor cellularity and vascularity through imaging methods such as diffusion and perfusion MRI. The neuro-imaging techniques we develop are used to determine whether brain tumors respond to therapy or signal when brain tumors are progressing. In addition to patient outcome studies, we study the histological features responsible for the imaging characteristics measures in-vivo. This provides us with a validation technique for assessing our imaging biomarkers.
My epilepsy research is mainly focused on development of image processing techniques meant to help clinicians better plan surgery and map out brain function.
