Research

I am a mathematically inclined applied computer scientist, with specific expertise in the fields of visualization, image processing, and image analysis. On the methodical side, I am particularly interested in tensor decompositions, higher-order tensor fields, and feature-based visualization; on the application side, most of my work has been in the area of neuroscience and medicine, especially on Diffusion Tensor Magnetic Resonance Imaging (DT-MRI) and High Angular Resolution Diffusion Imaging (HARDI). I am currently extending the scope of my work to a stronger use of machine learning techniques, modeling of uncertainty, and applications to a wider range of imaging modalities.
